Help with vbmail function

[reotto]

OK I took another route for some other features, but I am still stuck because I suck at JOIN. Here is the file or plugin I found and added, but now I need to find out how to add the "cellemail" field to the $subscriptions table so I can change the $subscription['email'] to $subscription['cellemail']. Here is spot where I think I need to pull the code for SMS 1.2 I loaded from.

PHP Code:

$vbulletin->db->query_write("
    CREATE TABLE IF NOT EXISTS `" . TABLE_PREFIX . "cellsettings` (
    `userid` INT NOT NULL ,
    `cellnum` VARCHAR( 20 ) NOT NULL ,
    `cellprovider` VARCHAR( 5 ) NOT NULL ,
    `cellprovidername` VARCHAR( 50 ) NOT NULL ,
    `country` VARCHAR( 50 ) NOT NULL ,
    `cellemail` VARCHAR( 100 ) NOT NULL ,
    `confirm` INT( 4 ) NOT NULL ,
    `smsonpm` INT( 4 ) NOT NULL ,
    `smscontact` INT( 4 ) NOT NULL ,
    `maxtexts` INT( 4 ) NOT NULL ,
    `dailytexts` INT( 4 ) NOT NULL DEFAULT '0' ,
    PRIMARY KEY ( `userid` ) 
    ) ENGINE = MYISAM 
"); 


But this part is throwing me for a loop as well.

PHP Code:

    if ($vbulletin->GPC['cellemail'])
    {
        $cellinfo = $db->query_first("
            SELECT cellnum FROM " . TABLE_PREFIX . "cellsettings
            WHERE userid = '" . $vbulletin->userinfo['userid'] . "'
            LIMIT 1
            ");
    
        // build their cell email address
        $shiznizzle = $db->query_first("
            SELECT email FROM " . TABLE_PREFIX . "cellproviders 
            WHERE id = '" . $vbulletin->GPC['cellemail'] . "'
            LIMIT 1
            ");
            
        $cellemail = "$cellinfo[cellnum]" . $shiznizzle['email'] . ""; 


The whole file for SMS 1.2 is attached. I tried a couple of different ways to do the join, but I could never get them into the subscription tables.
