MySQL Problem... Query not going through

I am having a problem with a simple set of queries. This is what is happening-

Query1 Implements

Query2 DOES NOT IMPLEMENT

Query3 Implements

Can someone tell me what I am doing wrong? Here is my code:

################################

Membership Acceptance Page

################################

###################

###################

Include ("../OUTSIDE/ROOT.php");

#########################

#########################

$TableName1 = "auth";
$Tablename2 = "profile";
$TableName3 = "bio";

$Link1 = mysql_connect($Host, $User, $Password);

mysql_select_db($DBName, $Link1);

##################

##################

$Query1 = "UPDATE $TableName1 SET confirm='1' WHERE auth.auth_id='$passvar'";

$Query2 = "UPDATE $TableName2 SET confirm='1' WHERE profile.profile_id='$passvar'";

$Query3 = "UPDATE $TableName3 SET confirm='1' WHERE bio.bio_id='$passvar'";

I am confused as to why Queries 1 and 3 go through but Query 2 does not?

$TableName1 = "auth";
$Tablename2 = "profile";
$TableName3 = "bio";

Should read:

$TableName1 = "auth";
$TableName2 = "profile";
$TableName3 = "bio";

Use errorchecking, if a query does not do what it should, that means the query is bad.
Print the query before you execute it.

A forum, a FAQ, email notification, what else do you need?

Man do I feel stupid LOL.

It is always something so minor with my errors like forgetting to place a semicolon and case sensitivity 🙁

Thanks guys!
