Here is another way...
ActiveSheet.Columns("AD").Hidden = True
By the way, the sheet doesn't have to be active to do this. Assuming Sheet1
is the ActiveSheet, here is how to hide Column AD on Sheet2...
Worksheets("Sheet2").Columns("AD").Hidden = True
or, if you want to do it via a variable...
WSname = "Sheet2"
Worksheets(WSname).Columns("AD").Hidden = True
