Hi Jason,
I tried hiding the select menu with with
<?php if (!empty($row_rssizedefault['size'])) { // Show if recordset not empty ?>
and also with
<?php if ($row_rsversion['version_id'] != "13") { // Show if recordset not empty ?>
Where id 13 is a zero value.
Both ways take the menu away and put the correct item in the cart. But they also take away a feature that price and item no. automatically adjust, when the user makes a version or size choice.
It seems like the select menu is made invisible not only to the browser, but also to some JavaScript, that seems to rely on a value (even a zero value) from the hidden select menu.
When using the style to hide the select menu, the adjusting feature still works, but the wrong item would be put into the cart, if a choice was made.
Sorry for being so confusing.
Just in case, I have attached a copy of the detail page.
