    Is it possible to be notified immediately if you're attaching a file that's not allowed?

    Asked by jodom on December 30, 2011 at 02:27 PM

    Sorry if this has been answered, but I’m at a loss.  I’ve created an upload option on my form with a max filesize of 40KB.  Is there anyway to let the user know immediately that the filesize is too large (if they attach something larger than the max)?  The problem I ran into as a test was that I filled the form out, uploaded a larger file than what’s allowed.  Upon clicking the submit button, it brought me to another page telling me that the file was too large.  It gave me the option to go back, and when I did, all the info I had filled out was deleted.  Any assistance or clarification is appreciated!

    Yes, just switch your single file upload tool into a multiple one. I think you've already figured it out. I have tested your form, attaching larger files and it seems to be working fine. Please check screen below:
