Thank you for responding.
You have me baffled. I was using the Tag for a Upper Case version of the text on the label. However I have removed all reference to Tag and no longer use that. I have scoured my code and cannot find any lingering reference.
The program runs from scratch each time and so nothing should linger.
Perhaps you could tell me the reason for your question, especially as I had been using Tag. I suspect I am supposed to have had a Eureka moment but I didn't.
