You will have to use jQuery or JavaScript to watch for the value change in one field, then populate your other fields.</p> <p><a href="http://stackoverflow.com/q/2004315/" rel="nofollow">http://stackoverflow.com/q/2004315/</a> </p> https://legacy.forums.gravityhelp.com/topic/how-to-use-input-in-one-field-to-populate-another#post-96148 Tue, 27 Nov 2012 10:01:49 +0000 chrishill123 96148@https://legacy.forums.gravityhelp.com/ <p>I have written the code to pull through a list of user IDs to a drop down box.</p> <p>Now I need to automatically populate two other fields (firstname and lastname) based on the userid selected in the dropdown box.</p> <p>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. </p>
