I am looking to transfer 90% of data from a source sheet to a destination sheet. Currently both sheets are empty. I plan to populate the source sheet by use of a form and hope the destination sheet populates with INDEX/MATCH. The problem I am running into is how to populate the primary key for the destination sheet, to drive the rest of the INDEX/MATCH calculations.
In testing, I received the #circular reference error for the PK on the destination sheet and a #blocked error for the one other index match calculation which references the PK.
If I decide to add the PK to both sheets (just 1-200 etc), then I think I solve those issues.... but then, when I perform the data entry with the form, how can I ensure the entries are recorded on each row that already has a PK on the source sheet? I did a test on this and it populated on the next available row, and did not copy to the destination sheet.
