I have a button which kicks off a VBA method which either hides or
unhides rows on a Worksheet.

I'd like to protect the worksheets but if I do an Error 400 occurs when
the VBA attempts to change a row's status from visible to invisible.

I've tried various protection settings but I still get the same error.

Is there one I should have tried?

Any suggestions? Should I have VBA unprotect/protect the sheet?
