Member tags

Hi!

I'm in the middle of creating a data centre and am having issues with the permissions. I have the split the datacentre into different properties and users can only view the files for the properties that they have registered for. I've used tags for this. It's working great, but the only issue i'm having is that the tag doesn't get automatically added to the member when they register. my registerration template is below as well as the diagnostics.

Any help would be much appreciated! Thank you!!
