I have custom form numbers.
I am using a workflow that pulls a number from a Master Number List assigns it to the form and then increments after a form number is assigned.
This is the method I used - https://www.habaneroconsulting.com/stories/insights/2012/nintex-workflows-makes-it-easy-to-create-an-auto-incrementing-column-in-sharepoint
However, twice I have been able to get duplicate numbers. How can I check to make sure that doesn't happen?
