hi @petercl14
your code could even have 3000 lines with each line containing 40 characters.
If you post your complete sketch as a code-section the height will be the half a computer screen.
Any texteditor has a search function where "a1" can be typed in to find where in thousands of lines your variable "a1" is used.
And with this simple technique your code can be analsysed.
You can go on for weeks with small text postings or code-snippets and loose the voluntary help of all users here still having not solved your problem.
or
You simply post your most actual and complete sketch as a code-section.
If you read this 3 minutes tutorial how to do it you will have posted your most actual and complete sketch with 5 mouse-clicks and 5 keypresses well fomatted as a code-section.
So what the hell is so complicated about doing this?
