The parts of my if formula work separately but not together. Err:509

[ZedicusAzul]

This is supposed to check column F for text, than return AA/BB/CC if blank or AA:BB:CC (A or P)M otherwise. All the parts work. The final formula does not. What am I doing wrong?

This is from sheet 10 of a book. The tested formulas show results from row 2 and 3. Columns A, B, and C have a 2 digit number. D has a alphanumeric. E is empty. F has AM, PM, or nothing. G has test formulas.

please provide a sample file (put it to a network share, and edit your question to add link to it). It’s error-prone to try to reproduce all that.

Err509 is a “Missing operator error”. You have missed & sign before the last F2 reference. The ending should look like Sheet10.C2 & " " & F2)
