[ic] mv_username, username

[Steve Graham]

Hello,

I am trying to get the value of a non-matching/failed username/password 
login attempt from the standard store login page:

I have tried
[cgi username]
[cgi mv_username]
[scratch mv_username]
[scratch username]

and they all return empty.

I need to test the username against another database and pop a message if it 
is found.

Any suggestions?

Thanks,
Steve
