Sheet Protection and Inserting Comments, Rows, Columns problem

Hi,

I'm not sure if I have a bit of a dodgy workbook here but the sheet protection code isn't working as expected.

I have a worksheet that contains a table of data. The cells within this table are unlocked but the headings and everything else is around it is locked.

I need to protect the sheet to prevent the user entering data outside of this table, no problem.

I need to allow the user to be able to use the AutoFilter, no problem.

I need to allow the user the ability to insert comments, problems start here:

With the sheet protection set like this I can now insert and delete rows, columns and indiviual cells. I can't seem to get it locked down right to allow comments but not inserting / deleting cells/columns/rows. I've even tried:

But no change. Anyone else any experience with this???

Thanks, TC

Presuming it must have been having a moment as it now works fine!
