I have the link of the webpart page where I have the editlistitem qlistform. (http://…./edititemstatusform.aspx)
I then add the ?ID=1 to the end of that URL and get directed to an error page saying no item exists. It may have been modified or deleted by the user.
I then checked my list to see what the different ID numbers were (there is an ID field I was not even looking at) and the IDs were like 35, 39 etc… so I tried doing ?ID=35 but still was directed to the error page.
