I have a form that allows people to register for training. I want people to be able to sign up for a specific class. The problem I am having is the form shows a lookup column that has the same title for all of the classes so when they sign up they don’t know which one to choose (see attachment). I would like to somehow connect the columns so when someone chooses one of the titles in the meeting column it automatically updates the Meeting2 column. If that is not possible I can always update the title to add the date.
When you create the lookup column, you can choose to include other columns from the lookup list. You should be doing that instead of trying to add a new column to the main list.
