Help with Touched() function in a script

Hey

So I have a basic script which is here (On pastebin for better formatting) https://pastebin.com/bM3xjHqM

and I was wondering how I would make it so during the period where the transparency is full and the cancollide is off that if someone touches it going through it (as they would), that it wouldn't start the timer again. Any tips on changing code or even changing loop if I have to?

Thanks, Sam
