Check Multiple elements by category for parameter existence

I am trying to check all the wall elements present in the model has required parameters value or not, but the code only checks first element obtained from all elements of category that is in this case 0 Wall 198694 and not the other wall element. Is there any way to check all wall elements instead of only first one. I am unable to share the dynamo file and excel as it says I am a new user hence I have attached a drive link below.
