Jim,

I believe you've misread the RT CustomField definition screen.
I've never used this feature before, but I read and interpret
it as follows:

It says (emphasis mine):

     RT can make this *custom field's values into hyperlinks to
     another service*. Fill in this field with a URL. RT will
     replace __id__ and __CustomField__ with the record's id
     and the custom field's value, respectively.

Let's say your CF is "Employee Number".

So, if you set "Link values to" as:

     http://service.example.com/lookup?empnum=__CustomField__

If I typed '430' into this CF as a value (as an end user),
it would show as a clickable link:

     http://service.example.com/lookup?empnum=430
