Using CASE and hiding a checkbox

Hi

I have some code which hides rows based on the entry into a cell, this works using the "Worksheet_Change(ByVal Target As Range)" and "case", however I can't get that to work when I want to hide a checkbox. Here is a sample of the code:

The code I have for checkboxes is:

However I can't get this to work when I include it at the end of a case. I've tried simply hiding the rows where the checkboxes are however they all bunch together and are still semi visible. The checkboxes I'm using are the activexcontrol type.

Any ideas?

Thanks
