Menu item with other activates hiden field
I am working on a new web site and one of the requirements are that I can bring up a group of 3 fields that a user can use to enter a product serial number schema. I read the the support post (Menu item with other activates hidden field) on your web site and that is very confusing to me. I understand that the wizard is capable of doing this and I get it. What would be an estimate from you guys to help me on getting thisdone?
I have attached the current file for your review, thank you for your help.
