How to pass a parameter with plus sign

[foxbox]

In A.ASP i show the user a list of records from a MS-SQL7 database TY. The user may select 1 record for update. This is done in program B.ASP
TY has one primary key field: tycode. Examples of codes are: 1x, 2x, 2-, 2+, 4x, 4-, 4+, etc.

When a user clicks on a link like this:
<a href=&quot;b.asp?tycode=4+&quot;>change</a>

b.asp is receiving &quot;4&quot; !

how do i solve this?

found it myself....
server.urlEncode(&quot;tycode&quot in my script,
which results in eg 4++ in the browser source...
