[demo version] String->Double?

I'm looking for a way to convert "TextFieldText$(gadget)" into a double for use with a spinner gadget, but when I try to use "Double[TextFieldText$(gadget)]" it tells me that it's "Unable to convert from 'String Array' to 'Double'".

I'm using the demo version as I said in the tiltle. Thanks for your time!

Try using normal brackets instead of the square ones

Double(TextFieldText$(gadget))

note syntax of TextFieldText$ should be

Function TextFieldText$( textfield:TGadget )

Worked. Thanks! :)

Or simply TextFieldText(gadget).toDouble()

Additionally, you may want to be sure that no non-numeric values are written to the TextField.
