Drawing a blank here...the overall project is a bit complex so I figured I would simplify things...
I have a custom list with a column that has a look-up field. I need to populate what is chosen there to populate another column in that same list.
So for example, I have a pull-down list called "Sandwich" and "Big-Mac" is chosen it would populate a "Sandwich Text" field.
I'm a SharePoint consultant and the farm is a Dev so I can I have all of tools available to me, SharePoint Designer 2013, Visual Studio, etc. :)
This would need to go into a workflow or into Visual Studio solution that I will deploy.
Eventually, this will be used to create an item in another list and populate "Big-Mac" in a column on that list but didn't want to confuse things here ;p
