    I need help

    Asked by bwhit1979 on April 02, 2013 at 09:03 PM

    We are a nationwide prepaid cellular service provider and provide PIN Cards for over 30 carriers nationwide. I want to be able to use a drop down menu and list all carriers we provide for, then once a carrier is selected, the customer has the option to add a denomination. Example... Verizon Wireless has 12 PIN Cards amounts to choose from... Is this possible?

    Yes, that is possible using our Conditional Logic (Show/Hide Condition). Show another field after an option is selected.
