[SOLVED] MySQL field

J!2.5 and CB 1.9

I have a field called cb_date in a field displayed on a tab.
Now i'm trying to use the same value of the cb_date in another tab.
I thought in use mysql field to do this.

I've created the query:

SELECT:cb_date
FROM:#c621_comprofiler
WHERE:id=$user->id

And i get no result.

If i put WHERE:id=521(one user id) the value is displayed.
What i'm i doing wrong?

SOLVED:
Find my own answer, sorry...

SELECT:cb_date
FROM:#c621_comprofiler
WHERE:id={USERID}

That did the trick...
