Please edit your post to add code tags and explain where the problem lies.

This one:

Something that might not be mentioned there - preferably use ctrl-T to autoformat your code prior to uploading. Your indentation is non-existent.

Maybe start with absolute values rather than percentage change - just check the level and send an appropriate message if a limit has been exceeded.

If you must use percentage increase, what's the timeframe and how do you reset the clock?
