Back to the drawing board??
I don't know Malc.

In post #14, you found out that the Start and Stop times were not being stored correctly from your button input routines, or they are getting changed somewhere else in the program.
And I agree, the routines I showed won't work if the preset times are wrong.

So why did you scrap the CheckTimes routine?
That isn't changing your start/stop times.

The latest code you showed would not compile.
Missing = signs for one (lightsetHR[fn]timeH).
