How to clear a text before a new text is placed in some spot

Hi all
Well after a short break am back to trying to sort this problem out.
Here is the new code that i have been trying, the attanSwitch
part has not been tested yet, will deal with that later.
i also have a short video of the display showing the pulsing\flickering
if i can work out how to send it lol.
Thanks for looking
Howard
