if else statement

I have gone through previous posts and pulled the code that worked, but it does not seem to work for me. My problem is the if statement is always false and it procedes to else. Can someone help me out.
Thanks
function BeforeAdd(&$values)

{
// Parameters:

// $values - Array object.

// Each field on the Add form represented as 'Field name'-'Field value' pair
//** Save new data in another table ****
global $conn,$strTableName;

if($values["BANR_INDEX"] == "'7%%%%%'")
{

$strSQLInsert = "update masterindex set

BANR_FUND = '".$values["BANR_FUND"]."' ,

BANR_ORG = '".$values["BANR_ORG"]."' ,

BANR_PROG = '".$values["BANR_PROG"]."' ,

BANR_LOC = '".$values["BANR_LOC"]."' ,

DE = '".$values["DE"]."' ,

StartDate = '".$values["StartDate"]."' ,

EndDate = '".$values["EndDate"]."' ,

OH = '".$values["OH"]."' ,

FY_YEAR = '".$values["FY_YEAR"]."' ,

Comments = 'Not Completed'

where BANR_INDEX=".$values["BANR_INDEX"];

db_exec($strSQLInsert,$conn);
//** Insert a record into another table ****
$strSQLInsert = "insert into masterindex (DE, Comments) values (NULL, 'Available')";

db_exec($strSQLInsert,$conn);
}
else

{

}
return true;
// return true if you like to proceed with adding new record

// return false in other case
}
