    Hi,
    I am trying to make a multiplication function, similar to a calculator. I need the text box on the left to be able to have numbers input, and then to click a button, and have the input number multiplied by thirty, and have the answer show up in a box next to it. Any Ideas

    you might want to try attaching this to the button that triggers that calculation as a simplistic solution:


    on (release) {

    //name the textbox for your input with a legal variable name

    myMulti = (parseFloat(TextField1) * 30);

    //name the textbox for your display, set its properties to dynamic text.

    DisplayField1 = myMulti

    }

    that should do it.

    >>P

    Hi, do you have any idea about this one

    Hi,
    I am building a calculator for a presentation, that will need to have a "," in the thousands place, and fill out to 2 decimal places. I have gotten the two decimal places thing worked out except for the fact that when the answer comes out to be , lets say 2.5, the display field shows 2.5.00. The basic layout of the calc is in levels. Level 1 input text + 25 * .0025 = whatever. There are 10 levels, and at the end, I have another field that dynamically shows each levels answers added together. I will put my code at the bottom of this message, Don't laugh at me, I honestly don't know what I am doing, but have been searching through the boards peicing together information, so I am quite proud that I have any functionality at all. Please help. I still need to figure out how to fix the coma issue, and the extra .00 when the decimal ends up with .5

    on (release) {
    nextFrame ();
    myMulti = (parseFloat(TextField1)*25*.0025);
    myMulti2 = (parseFloat(TextField2)*25*.0025);
    myMulti3 = (parseFloat(TextField3)*25*.0025);
    myMulti4 = (parseFloat(TextField4)*25*.0025);
    myMulti5 = (parseFloat(TextField5)*25*.0025);
    myMulti6 = (parseFloat(TextField6)*25*.0025);
    myMulti7 = (parseFloat(TextField7)*25*.0025);
    myMulti8 = (parseFloat(TextField8)*25*.0025);
    myMulti9 = (parseFloat(TextField9)*25*.01);
    myMulti10 = (parseFloat(TextField10)*25*.05);
    DisplayField1 = Math.round(myMulti*100)/100;
    DisplayField2 = Math.round(myMulti2*100)/100;
    DisplayField3 = Math.round(myMulti3*100)/100;
    DisplayField4 = Math.round(myMulti4*100)/100;
    DisplayField5 = Math.round(myMulti5*100)/100;
    DisplayField6 = Math.round(myMulti6*100)/100;
    DisplayField7 = Math.round(myMulti7*100)/100;
    DisplayField8 = Math.round(myMulti8*100)/100;
    DisplayField9 = Math.round(myMulti9*100)/100;
    DisplayField10 = Math.round(myMulti10*100)/100;
    myMulti11 = (parseFloat(DisplayField1)+(DisplayField2)+(Displa yField3)+(DisplayField4)+(DisplayField5)+(DisplayF ield6)+(DisplayField7)+(DisplayField8)+(DisplayFie ld9)+(DisplayField10));
    DisplayField11 = Math.round(myMulti11*100)/100;
    if (myMulti10*10 == Math.round(myMulti10*10)) {
    DisplayField10 = myMulti10+".00";
    }
    if (myMulti9*10 == Math.round(myMulti9*10)) {
    DisplayField9 = myMulti9+".00";
    }
    if (myMulti8*10 == Math.round(myMulti8*10)) {
    DisplayField8 = myMulti8+".00";
    }
    if (myMulti7*10 == Math.round(myMulti7*10)) {
    DisplayField7 = myMulti7+".00";
    }
    if (myMulti6*10 == Math.round(myMulti6*10)) {
    DisplayField6 = myMulti6+".00";
    }
    if (myMulti5*10 == Math.round(myMulti5*10)) {
    DisplayField5 = myMulti5+".00";
    }
    if (myMulti4*10 == Math.round(myMulti4*10)) {
    DisplayField4 = myMulti4+".00";
    }
    if (myMulti3*10 == Math.round(myMulti3*10)) {
    DisplayField3 = myMulti3+".00";
    }
    if (myMulti2*10 == Math.round(myMulti2*10)) {
    DisplayField2 = myMulti2+".00";
    }
    if (myMulti*10 == Math.round(myMulti*10)) {
    DisplayField1 = myMulti+".00";
    }
    }


    Thanks so much for your help.
    Flashkit is awesome.

    Wow, that's long! Here's my take on it:

    Code:
    sum = 120120120;
    
    function format(x){
    	l = x.length;
    	var r = "";
    	for(var i=l;i>-1;i--){
    		r = x.charAt(i) + r;
    		r = (i%3==1 ? "," : "") + r;
    	}
    	return r;
    }
    
    
    sum = format(String(sum)); 
    // It takes a string number for input, and outputs a string
    
    trace(sum);

    Hi, Sorry about the repeat post

    Hi,
    Well, I am not exactly sure what to do with the code you gave me. where should I add the code? In a button, or frame?
    Quite honestly, I am a little green when it comes to coding, and don't know what a lot of the stuff means yeat. I will add include one level of my calc for an example, and you can let me know how the code should be entered.

    I have an input field called TextFeild1
    I have a dynamic text box called DisplayField1
    I have a line of code that states

    myMulti = (parseFloat(TextField1)*25*.0025);

    DisplayField1 = Math.round(myMulti*100)/100;

    if (myMulti*10 == Math.round(myMulti*10)) {
    DisplayField1 = myMulti+".00";
    }
    Thanks for the help
