Fix My Simple Pine Script

I have basic knoweldge of Pine Script for TradingView and have produced a simple strategy script. However, my script is not functioning as intended. It doesn't appear to be entering and exiting positions or plotting properly.

I think this will be a rather simple fix for an experienced scripter in Pine as my script is not long (50 lines) or complicated at all.

I will be happy to share both the code and pseudo-code to help you fix the issues.
