URL Rewriting in Global.aspx file not working Correctly

Question

I am implementing url rewriting in Global.aspx as follows below

 

1. routes.MapPageRoute("PartyGames-listing", "Party-Games/{TitleHeading}", "~/PartyGames.aspx");

 

2: routes.MapPageRoute("Party-Games-Detail", "Party-Games/{ReviewTitle}", "~/PartyGamesDetail.aspx");

 

 In these rules page name is different when i am redirecting on second page, But it is mapping first url not mapping to second rule. it is redirecting first page instead of second url.

How to resolve this problem  

 

 

 

Thanks
