Can you enable maximum debug and provide the call stack please?

[EricdeWaal]

With max debug, an extra error appeared at the top of the screen:

I see what the problem is with the array_key_exists. The value produced by the calc element is null. I need to determine the best way to solve this.

[EricdeWaal]

Hi Alex,

As far as I can see this was not solved, or did I miss it?

[skurvish]

Not yet, on my list.

[skurvish]

@EricdeWaal would you unzip the attached into your joomla root and test for me. It is working now on my site with this change.
calc.zip

[EricdeWaal]

@skurvish Yes, I can confirm this works.
Closing it now.
Thanks!
