Please advise on how to fix.

We have commented out line 11 temporarily in order to get our client's shop back working again, but will still need a fix.

This did not resolve the issue.

I have left line 11 in the show_quantity.php view so that you can see the direct issue. Please respond ASAP so that I can comment it back out again so that the shop is back up and running for our clients.
