Thank you for the reply Markus,

I have created intermediate rules and assigned the value like the following

For the second part, I have created an expression which is always true (I'm
assuming to be)
[image: Inline image 3]
I have tried this and it doesn't show the score. I there any thing that I'm
missing. Please let me know, thank you for the help.
