search all instance for regex value sql server

Hi I asked this on stack overflow but no answer as yet... i'm trying to create a script that will allow me to use different regex to search for different values in dbs across an instance... i.e. phone numbers, card numbers etc. I think i've nearly cracked it I just need some help, i'm not sure the regex will work properly... pasted my code below... thanks!
