I initially misread this:
"Zone is a number. Both plot and position are text fields." ... 'seeing' Plot as 'number', which happened after you posted:
"I did not tell you that I need to hard code the value for Position right into the statement. The value for Position is text and needs to be POS011" ... I accidentally Plot to number ... wherein you can see that I had Plot as text here @
http:#a25606822 ... and I was the one who asked:
"What are the Data Types of Plot, Zone and Position ?"
So, that's what happened.
