Update button not redirecting to correct page
Hi - I hope this is an easy solution - I've been trying to get this to work all morning, but no luck, so please help. Quite simply, I want the update button (and the cancel button) on my inventory_Update.php page to redirect to order_Detail.php after update. I've passed the orderID in the query string and the cancel button redirects fine however the orderID doesn't carry over on update. Please tell me what I'm doing wrong. Relevant pages attached.
