Is there anything obviously wrong in this code?

I have two custom buttons, HOLD and HIRE. HOLD is working fine. HIRE is reverting to HOLD. Is there anything obviously wrong with my code? If so, what is the fix? This is in LIST PAGE -> BEFORE RECORD DELETED in the event editor.
//delete records

if(@$_POST["a"]=="delete")

return true;

//

//update records

global $strTableName;

//

if(@$_POST["a"]=="Hold")

{

// set isHeld to '0' meaning, is not on hold

$sql = "UPDATE CCEmployerView SET isHeld='"."1"."', holdby='".$_SESSION["ID"]."',

holddate=now() where CandidateCCID=" . $deleted_values["CandidateCCID"];

CustomQuery($sql);

}

// move all data to CCEmployerView table and delete from CCEmployerHold table

{

$sql = "INSERT into CCEmployerHold
