Lookup column with cascading - filter problem

(0) ShareShare
ReportReport
Posted on by Community Power Pla... Microsoft Employee

Hi,

 

I found a nice tutorial for a cascading lookup list. I use this tutorial Link but my last formula is wrong, what do i wrong?

This my formula: 

Filter(Show Columns('Applicants List', "Title", "ID", "ApplicationsJobPositionLookup"), ApplicationsJobPositionLookup.Id = JobPositionDropdown.Selected.ID) It

This is the code for my second lookup column. This first column works fine, this is my formula

 

ShowColumns('Job Positions', "ID", "Title")

I have 3 lists:

List 1 - Job Position - Title column

List 2 - Application List - Title column and 1 lookup column to Job Position

List 3 - InterviewSchedule - 2 lookup columns to the first two lists

    First check why 'ShowColumns' has the space in your formula?
