Dialogue box results "not a number"
Hello! I'm new to InDesign scripting (as of today) and am having difficulty with using dialogue box results in my script. The script I've put together creates calligraphy line guides down a page, and I got it working fine but then wanted to be able to specify the distances between the lines in a dialogue box rather than in the script, and it's now not working.
I know that everything from line 43 downwards works if I remove the dialogue box and create the variables using parseInt() rather than pulling them in from the dialogue box, but as soon as I try to use the values from the dialogue box it comes up with error 30491 on line 60 that ascenderHeight is Not a Number (and so it presumably can't use it to calculate within geometricBounds). I've tried converting a test variable to an integer beneath line 43, but it's not making any difference. Originally I was using the measurementEditBox as in the InDesign Scripting Tutorial, but figured that the integer one would remove any excess baggage. If someone could let me know where I'm going wrong, I'd really appreciate it!
var myDialog = app.dialogs.add({name: "Set line guide parameters",canCancel:true}) ;
with (myDialog){
//Add labels dialog column.
with(dialogColumns.add()){
staticTexts.add({staticLabel:"X-height to ascender (mm)"});
staticTexts.add({staticLabel:"X-height (mm)"});
staticTexts.add({staticLabel:"Descender height (mm)"});
staticTexts.add({staticLabel:"Slant angle"});
}
//Add entry dialog column
with(dialogColumns.add()){
//Create integer & angle entry fields.
var ascenderHeightField = integerEditboxes.add({editValue:5}) ;
var xHeightmmField = integerEditboxes.add({editValue:5}) ;
var descenderHeightField = integerEditboxes.add({editValue:2}) ;
var slantAngleField = angleEditboxes.add({editValue:-30}) ;
}
}

var myResult = myDialog.show() ;
if (myResult == true) {
//Get the values from the dialog box controls
var ascenderHeight = ascenderHeightField;
var xHeightmm = xHeightmmField;
