For some reason, I am not able to open your screenshot.

I had an EA that was working and is the left area dealing with VWAP, etc. I added the right area in attempt to plot a slope (from existing working code example). I added the constants and variables for the slope as well.

Can someone take a look because the EA now gets cannot load error in MT4?
