Apologies for the delay in posting as I have been away on holiday and didn't get a chance to put the final part of this puzzle in place before leaving. I have tried the next day delivery option as you have specified but have not gotten it to work yet. You mentioned that I need to put a hidden field on the confirm page with the following code:
<input type="hidden" name="nextDay" value="<?php echo isset($_POST['nextDay']?$_POST['nextDay']:""); ?>" />
I think this is probably the problem as it states PHp but I am using ASP. Could you please let me know how this code should read for ASP?
