I have a table, tbSamples, with a field UserID. when a new recorded is added
I would like to default the User ID of the person loged on, adding the record.
I have tried using; =CurrentUser() , this only returned Admin regardless of  
who was logged on.
It was suggested that I try this web site;
http://www.mvps.org/access/api/api0008.htm
I created a module, modUserID and pasted in the code from below.
This is where I come un-stuck. How do I activate this module to default the
User ID into the field?
I am using Windows and Access 2000.
Any help appreciated.
