Hmm okay, is it possible for you to give me an example with a simple GUI which clears checkboxes or radiobuttons with a button? Because i tried setting to default earlier but couldn't get it to work.

Oh i do have one more question though. Is there a way i could make a clear button to reset the radio buttons, check buttons and the calculated sellingPrice?

DUDE! YOU are a genius!! Thanks so much!! really appreciate your help!

THANK YOU!!!

Ok, what i've been trying to do is get the radio buttons 'standard, large and superlarge' to register with values '10, 20 and 25' as variable d so when i enter it in 'area = (pow(3.1415*(d/100)),2)/4' i can get a value for the area. I've been having a bit of trouble due to my lack of programming expertise.
help would be greatly appreciated

Ok thanks for the info. I'll give it a shot!
