What is wrong when I see this error message? I was tryng to run the query I created and this popped up. I needed the query to use two fields a po received units field and a fiscal week field. Could this be the problem? If so, how can I fix the query to show me the # of units received by the fiscal week? Do I need to include other fields to get the result of the # of units recieved by fiscal week? Thanks in advance.
