Guys,
I am using Nintex workflow 2007 on SharePoint 2007 instance. I have several approvals in my workflow where the approver can attach the document along with other columns. What I need to do is to make a document attachment field mandatory so that if the user does not attach a file and submits he will get an error message right away on screen.
Please advise on how I can achieve this. I am can custom code as well.
Cheers.
Umair
