The one issue I see is that you have "UNION%20SELECT%20" as what you are searching for.

 

But you also have "stringtolower" which would change the URI to all lowercase, and therefore "UNION%20SELECT%20" would never actually show up since it is in CAPS.

 

Change that to "union%20select%20"

 

Hope that helps! If it does please up-vote and select this answer, it'd be greatly appreciated!
