IIS 10 - URL Rewrite Rule for Search Query, not working?

Hello, All.
(The development is done in ASP Classic (VB), in case I need to do something within the code.)

In the website, our search string is displayed as such.

Main.asp?Type=Results&Submit=Search&Term=KISS&Cat=3

Our URL Rewrite is this.

Pattern: Search/([_0-9a-z-(-)-,-]+)/([_0-9a-z-(-)-,-]+)
Rewrite URL: Main.asp?Type=Results&Submit=Search&Term={R:1}&Cat={R:2}

Screenshot of the RULE

How can I make the Search Query work, so that when you click search, it rewrites the URL to this?

Search/KISS/3

Thanks.
Wayne
