    Variables: adding a variable to another set of variables

    Hi, im trying to add a set of variables to create a total how i've done it is:

    _root.total = _root.variable1+_root.variable2+_root.variable3;

    etc...

    however... it does not work!!!!!!

    instead of adding the variables up and gettin the sum instead it just adds the number from variable1 variable2 and variable3 to _root.total

    EG.

    total = 0
    variable1 = 2
    variable2 = 3
    variable3 = 4

    then it makes it like this..

    total = 0234

    i've tried doing it many different ways but it just wont work the way i want it to. plz help, its probably something stupid that i've forgotten, all helps appreciated. thanks.

    Make sure that variable1-3 are number types. In their definition use:

    var variable1:Number = 2;
    var variable2:Number = 3;
    var variable3:Number = 4;

    Or just cast them as numbers:
    total = Number (var1) + Number (var2)...

    Sorry for the double post... but, apparently i cant edit my posts after 10 minutes has passed. Anyway, your method worked perfectly thanks for the help. BUT is there anyway that i could make it so the total = Number(var1)+Number(var2);

    AND

    The variables as input text fields and whenever the variables in the input text field are changed the total is automatically updated?
