Need help with VBA code. Tons of code seperated in two, second part of code doesn't work.

It will basically do that same thing for the rows, but it will hide columns and rows instead. It would be for a sheet called "Daily Sales Tracking".
So if I4 is blank, then hide columns J & K and rows 382 & 383. I5 would hide columns P & Q and rows 384 & 385, etc.
