How to use input in one field to populate another

    I have written the code to pull through a list of user IDs to a drop down box.

    Now I need to automatically populate two other fields (firstname and lastname) based on the userid selected in the dropdown box.

    For the life of me I cannot seem to get this to work. I think I'm over complicating things so can someone walk me through how to use the value of a field, before submission, for use in another field.

  2. There is nothing like this built in to Gravity Forms. You will have to use jQuery or JavaScript to watch for the value change in one field, then populate your other fields.
