SharePoint Designer Form with Multiple attachment buttons
I have a custom form with 3 columns and each one has the option to add files/attachment to the list.
when creating a new item, I am able to attach a file in the first column, however, if I add an attachment in the second or in the third column I am getting the following pop message
" You must specify a non-blank value for File "
screenshot of the form from the SharePoint list and the code from the designer is attached below.
any suggestions on how to fix this problem?
