DarkPrince2005 Posted March 21, 2008 Share Posted March 21, 2008 Can somebody please help me with a script? i've got a drop down box in a form, but i want to auto generate the text in 3 textboxes depending on the selection made. e.g. if option 1 is selected the first textboxes text should be set to 150, and the second 250, and the third should show the sum of the first and second textboxes values.
