Sorry! </p> https://www.machform.com/forums/topic/another-form-logic-request#post-2408 Sat, 19 Jul 2008 00:51:27 +0000 walags 2408@https://www.machform.com/forums/ <p>well i really wasn't expecting to be able to do my last request, but yall knocked it out pretty easily. i'v got one more thing i would like to do. in this example you have 4 drop-down elements. the first three have two options, and the last has all options. the forth drop-down is a required field...</p> <p>DD1: A or B<br /> DD2: C or D<br /> DD3: E or F</p> <p>DD4*: A or B or C or D or E or F</p> <p>Is there a way to prohibit a user from selecting an option in DD4 which was not selected in a previous DD? and customize the error message.</p> <p>This logic would be icing on the cake for me, and would need a paypal link to show my appreciation! </p>
