Cycle through controls and clear tag

[glgcag]

I have put together a function that clears controls on my unbound form, but I'm having a strange issue- when I clear my controls (acTextBox, acCheckBox, etc.) I set it to null, but if I try to set the same control's tag value to null it errors out. If I set the control's tag value to an empty string, it works fine.

Is this normal, and is it because the tag property does not have the same characteristics of the control it is the tag of?

Thanks for the help in advance!

The Tag property is a string and can't be set to Null.
