Reports with URL Buttons

I was trying to use this video to make a custom URL button to link to a report on another table. the cod I sued is below. It seems to not give me an error when I put in the formula but when I use the button it tells me that the application does not exist - which is a weird error lol.

URLRoot() & "db/" & [Passings] & "?a=q&qid=11"

Please let me know what you think here and if I'm just going crazy
