Searching a column in table A using data from a column in table B
Hi Anonymous
"Custom1" is not created with adding a custom column. It is created in the formula bar directly just like below. You can right click #"Renamed Columns2" step, select "Insert Step After" then modify the code in the formula bar.
For the second step, it is created with adding a custom column. But it is not based on the "Custom1" step. Instead, it is based on the previous step of "Custom1". You need to modify the step name.
You can also edit the code in Advanced editor directly. It looks like this.

Ive been trying to get this to work but running into an expression error.
= Table.AddColumn(#"Renamed Columns2", "SFID", each let vsubject = [Subject] in List.Last(List.First(List.Select(Custom1, each Text.Contains(vSubject, _{0})))))
Expression.Error: The name 'vSubject' wasn't recognized. Make sure it's spelled correctly.
The custom list also broke my visuals as I have other columns that are referenced.
