The code looks great, unable to compile, and thus unable to create zip archive. The error comes up ad "297:" with additional text. The line numbers when looking at code do not go up to 297. 12Blocks highlights the IF ELSE block for "redLEDState2==0" in the second START code section. I upgraded to 2.1.9/Latest beta to see if that would help, it did not. It is taking too long to register a button push with 100u caps added. I had to add caps for reliability.
