Multiple parameters in Google Assistant SDK - json

Question

This is sort of a follow up question to this. I want to use 2 parameters in my assistant command. When I used only 1 parameter for a command, code worked flawlessly. However, when I added a second parameter to query pattern, the pattern was never detected. I have pasted my actions json file below. What have I missed?

Do you need the parameters in parenthesis? It should be fine to have it without parenthesis, or adding a ? at the end will make it a wild card.
