Evening all, I have a piece of code which creates coordinates based on a variable pitch centre dimension along with variable numbers of positions within the rows and columns (this runs too slow for my liking, but thats one for another day)....

I need to flip the coordinates about a horizontal centre line which would be AG158 to CD158 and i'm struggling to find suitablably adaptable code.

Lets say for example AG158 contains -300,-25 AG157 would need to be -380,25

The X & Y coordinates are variable....

Thanks in advance
