Hello,
I need a popup 'yes/no' box that will alert a user that a field was left blank.
"No Receipt file uploaded, was this your intention?' Yes - No
So I need to check the value of a field, if blank I need to send this message option to the screen.
I had it working on my local machine with the use of a msgbox, but it does not work on the production web server.
Should this be done in JavaScript, or does AJAX offer something I can use?
Thank you
