Vars not updating constantly

[Creative Action]

I have variables some of which have values derived from dynamic text boxes with instance names. Then some var = (calculations) and some "if" statments. Finally a final value is derived and passed to a movie. The problem is that my trace statments show that the values are calculated once, then no more. Does this need to be in a onEnterFrame function? I tried that but it didn't work, although I made have made a typo.

Here's the code. If the solution is still obscure I can add the rest, or even a .fla.

Thanks a lot, I'm struggling but moving forward on this project.

var sunTime = 0;
sunTime = (sunMinutes+(sunHours*60));
trace ("a"+sunTime);
    if (ampmthing = true) {
        sunTime = sunTime+720;
        trace ("b"+sunTime);
    }    
    sunTime = sunTime-300;
    trace ("c"+sunTime);    
    if (sunTime<0) {
        sunTime = (sunTime+1440);
        trace ("d"+sunTime);
    };
trace ("e"+sunTime);
_parent.sun.gotoAndStop(sunTime)

I don't understand exactly your script but you have errors:
if (ampmthing = true) {
must be
if (ampmthing == true) {

Thank you cancerinform (in the wrong forum too I realized). I will change that now.

Delayed response due to another project.

Good catch, but still doesn't work. Here's the whole piece of code, which works except for sending the sun movie to the correct position based on the digital clock readout. Some stupid mistake I'm sure. I'm a rank amateur, wrote this mostly on my own, so it might look a little dumb.

stop();

var mrotate = 0;
var sunMinutes = 0;
var sunHours = 0;

//Move hands to analog minutes
minutesB.onPress = function() {
    var mth = 0;
    var mxmin = 104;
    var mymin = 91.5;
    minutesB._x = mxmin;
    minutesB._y = mymin;
    minutesB.onEnterFrame = function() {
        mth = Math.atan2(_ymouse-mymin, _xmouse-mxmin);
        mrotate = mth*180/Math.PI;
        minutesB._rotation = mrotate;
    };
};

//Sets digital minutes
minutesB.onMouseUp = function() {
    delete minutesB.onEnterFrame;

    if (mrotate<0) {
        displayMinutes_txt.text = Math.round((mrotate+360)/6);

    } else {
        displayMinutes_txt.text = Math.round(mrotate/6);
    }
    
//variable for movie timeline
    sunMinutes = displayMinutes_txt.text;

    if (displayMinutes_txt.text<10) {
        displayMinutes_txt.text = "0"+displayMinutes_txt.text;
    }
};

//Move hands to analog hours
hoursB.onPress = function() {
    var hth = 0;
    var hxmin = 104;
    var hymin = 91.5;
    hoursB._x = hxmin;
    hoursB._y = hymin;
    hoursB.onEnterFrame = function() {
        hth = Math.atan2(_ymouse-hymin, _xmouse-hxmin);
        hrotate = hth*180/Math.PI;
        hoursB._rotation = hrotate;
    };
};
//Sets digtal hours
hoursB.onRelease = function() {
    delete hoursB.onEnterFrame;

    if (hrotate<0) {
        displayHours_txt.text = Math.round((hrotate+360)/30);
        
    } else {
        displayHours_txt.text = Math.round(hrotate/30);
    }

//variable for movie timeline    
    sunHours = displayHours_txt.text;

    if (displayHours_txt.text<10) {
        displayHours_txt.text = "0"+displayHours_txt.text;
    }
};


//Manual switching beteen AM and PM
ampmmov.onRelease = function() {

    if (ampmthing == false) {
        displayAmPm_txt.text = "pm";
        ampmthing = true;
    } else {
        displayAmPm_txt.text = "am";
        ampmthing = false;
    }

};

//Code that moves playhead to correct movie frame

var sunTime = 0;
trace ("aa"+sunTime);

sunTime = (sunMinutes+(sunHours*60));
trace ("a"+sunTime);

    if (ampmthing == true) {
        sunTime = sunTime+720;
        trace ("b"+sunTime);
    }
    
    sunTime = sunTime-300;
    trace ("c"+sunTime);
    
    if (sunTime<0) {
        sunTime = (sunTime+1440);
        trace ("d"+sunTime);
    };

trace ("e"+sunTime);
