I'm having a issue where i have a screen field 'G_COUPON' that when the person initially sets the value to say 'zzz' it gets passed to SAP on the button submit. The issue is that 'zzz' coupon is incorrect therefore will return them back to the shopping cart so they can correct the incorrect code to say 'yyy' but when the user hits submit this time the new 'yyy' code is not read in from the <input> field and SAP still thinks the 'zzz' code is inputted.
Has anyone ever run into an issue like this were a field will pass the correct value on the initial submission of the page but if you return back to the page to change the value and resubmit it's still keeping the old value and not reading in the new value that was changed?
