Question

If a checkbox is selected can it perform a calculation?

I would like to have a check box field and if selected it would return a value in another field. Eg. if selected take the value in field "subtotal" and multiply it by 0.05. return that value in field "GST". Is this possible.

Yes, but it's better to do it from the calculation event of the target field ("GST") then from the check-box itself.

What should be the value of this field if the box is not ticked, though?

The value would be $0.00

OK, then use this code as the custom calculation script (you'll just need to adjust the names of the fields involved to match the actual names in your file):

var subtotal = Number(this.getField("subtotal").value);
event.value = (this.getField("CheckBox1").value=="Off") ? 0 : subtotal * 0.05;
