Hi Jason,
<?php echo WA_PP_ECO_GetValue($WA_PP_ECO_DoResult, "GrossAmount") - WA_PP_ECO_GetValue($WA_PP_ECO_DoResult, "FeeAmount"); ?>
This does not work, it always says, column donation cant be null.
if I take only one of em it works.
very strange.
ps. I use it in the confirm page, where the wizzard uses the database input, too.
Cheers,
Denis
