Using A Varrible In A File With Include

The file that I am trying to use is as below:

Link_Cat_6.asp

<!--#include file="../display_links.asp"-->

<%Dim Link_Category_ID%>

<%Link_Category_ID = 6%>

I am trying to use the varriable Link_Category_ID on the included page display_links.asp in an SQL string.

I am getting an error in the SQL string WHERE clause saying that the varrible Link_Category_ID doesnt exist i.e. it says that the clause is incomplete.

I can't see why its not accepting the varriable in the file.
