UI button programming

[Maple Stirrup]

I'm trying to grab a number from the user, default of 1, with buttons next to it that increase or decrease that number

I don't believe I'm even close yet, the number displayed in the UI doesn't change here, also, I'm not sure it's even a number, but text instead.  I'm still very new at this, everything is probably pretty crude.

w = new Window('dialog', "Gadget");

  w.grp1 = w.add('group');

  w.grp1.orientation = "row";

  w.grp1.alignment = "right";

    w.grp1.add("statictext", undefined, "Left Offset:");

    var leftoffset = w.grp1.add("edittext", undefined, 1);

      leftoffset.characters = 3;

      leftoffset.active = true;

    var grp1up = w.grp1.add("button", undefined, "+");

      grp1up.onClick = leftoffset = leftoffset + 1;

    var grp1down = w.grp1.add("button", undefined, "-");

      grp1up.onClick = leftoffset = leftoffset - 1;

Another later goal is to have a checkbox in the UI near the beginning, that allows the button presses to increase the numbers by 0.25's instead of 1's

[Silly-V · Accepted solution]

Your onClick code has to be revised to be set to a function like this:

grp1up.onClick = function(){

     leftoffset.text = (leftoffset.text * 1) + 1;

}

the * 1 is to turn the string from UI into a number you can calculate with.
