Hi Markus,

I have made the changes you have suggested, but it doesn't work, I've tried
to assign this rule to another data element, the score element greys out
but the score doesn't show up. Is there any other way to debug program
rules and check what value is being stored. I also tried to make the
changes you have suggested and it didn't work.

Please find the attached screenshots. Thank you for the help.
