I am using SharePoint 2013 and Nintex Workflows 2013. I have List A and List B. Both of them are in the same site. I want a Total field from List A to be displayed in the List B SharePoint form based on criteria. I also don't want the user to be able to save the form if an Amount field is greater than the Total field that was bought over from List A. I need this to happen on Create and Modify. How can I do this? Please give me code and screenshots if possible.
I hope this makes sense.
Thanks in advance!!!!
