You can pass a setting to prevent the shipping address from changing.
You just have to add this with the other parameters being passed:
$nextIndex = count($WA_PP_ECO_Set_params[0]);
$WA_PP_ECO_Set_params[0][$nextIndex] = "addressoverride";
$WA_PP_ECO_Set_params[1][$nextIndex] = "1";
If you can't spot where to add it, just attach your confirm.php page and I can give you a line number. You can add it right after the address or phone number.
That will prevent them from updating the address once passed to paypal.
Did this help? Tips are appreciated...
