Calculation resulting from checkbox selection in a PDF

[DisneyMickeyGirl]

I am very new at creating custom calculation scripts, and I don't know how to do the following:

I need to calulate the total of all fees associated with the boxes checked:

    

The checkboxes are titled Checkbox1, Checkbox2, etc.

The exception is the custom fee boxes, that's where I'm getting stuck. If those checkboxes are clicked, they will enter a dollar amount in the FEE1-FEE3 fields.

The Total will be calculated in a "Total Fees" field.

Is this possible?

Thank you VERY much for your help!

You can do it using this code (I assumed the names of the check-boxes are Checkbox1 to Checkbox10):

var total = 0;
for (var i=1; i<=7; i++) {
	var v = this.getField("Checkbox"+i).valueAsString;
	if (v!="Off") total+=Number(v);
}
if (this.getField("Checkbox8").valueAsString!="Off") total+=Number(this.getField("FEE1").valueAsString);
if (this.getField("Checkbox9").valueAsString!="Off") total+=Number(this.getField("FEE2").valueAsString);
if (this.getField("Checkbox10").valueAsString!="Off") total+=Number(this.getField("FEE3").valueAsString);
event.value = total;

In order for it to work, though, you must set the export values of the first 7 check-boxes as the price for that item (without the dollar symbol, just as a number).
