I have 2 SP Lists.
SP 1 - stores data about exam dates
SP 2 - stores data about students
SP 2 has a lookup field that shows the C_Codes from SP 1.
SP 2 also stores data about staff member who is associated with exam. the data is stored in SP 1, but on my PowerApp, it copies that data and saves it into a field on SP 2.
If member of staff was to leave and new member of staff was added, I need a way to update records with new info. SP 1 would get modified, then flow would run and update all records that match the selected C_Code. But I am struggling to get this to work.
Here is what I have:



When it runs, the Assessor doesn't update.
Can anyone advise on what I am doing wrong?
thanks
