Checkout Shipping Options if statement

I am trying to list 2 sets of options for shipping to our customers. Each draws from a recordset in the shipping tables. I want the US options to show up if the customer is in the US and all other options to show up if the customer is international based on a boolean in the shipping table that marks options as US.

My code isn't working. Both options show up no matter what the country ID is in the customer's table. It looks like a simple statement would work, but I'm not proficient in PHP.
What am I doing wrong?

------begin-----------

<?php if ($row_WAATKcustomers['CountryID'] != 236) { // Show if recordset not empty ?>
<select name="shipTypeList" id="shipTypeList">
<option value="">Choose Shipping</option>
<?php
do {
?>
<option value="<?php echo $row_rsShipTypeList['ShipTypeID']?>"><?php echo $row_rsShipTypeList['ShipTypeName']?></option>
<?php
} while ($row_rsShipTypeList = mysql_fetch_assoc($rsShipTypeList));
$rows = mysql_num_rows($rsShipTypeList);
if($rows > 0) {
mysql_data_seek($rsShipTypeList, 0);
$row_rsShipTypeList = mysql_fetch_assoc($rsShipTypeList);
}
?>
</select>
<?php } // Show if recordset not empty ?>

<?php if ($row_WAATKcustomers['CountryID'] = 236) { // Show if recordset not empty ?>

<select name="shipTypeList" id="shipTypeList">
<option value="">Choose Shipping</option>
<?php
do {
?>
<option value="<?php echo $row_rsShipTypeUS['ShipTypeID']?>"><?php echo $row_rsShipTypeUS['ShipTypeName']?></option>
<?php
} while ($row_rsShipTypeUS = mysql_fetch_assoc($rsShipTypeUS));
$rows = mysql_num_rows($rsShipTypeUS);
if($rows > 0) {
mysql_data_seek($rsShipTypeUS, 0);
$row_rsShipTypeUS = mysql_fetch_assoc($rsShipTypeUS);
}
?>
</select>
<?php } // Show if recordset not empty ?>

--end -

The problem looks to be how your second if statement is formed, you have it like this:

<?php if ($row_WAATKcustomers['CountryID'] = 236) { // Show if recordset not empty ?>

This is not comparing the countryID to 236, you are trying to set it to 236. The code after this if statement will execute always regardless. You need to update this to check if it is equal to this value like this:

<?php if ($row_WAATKcustomers['CountryID'] == 236) { // Show if recordset not empty ?>
or
<?php if ($row_WAATKcustomers['CountryID'] == '236') { // Show if recordset not empty ?>
