Send Arguments In A String

I have a static URL with two links:

<a href="someASPpage.asp?category=yes">Show category 1 </a>
<a href="someASPpage.asp?category=no">Show category 2 </a>

They both pass an argument to the “someASPpage.asp”. The URL that retrieves the passed argument should be one of two frames in a frameset. Therefore I also have the frameset called “frameset.asp” and frame1 (that should hold the “someASPpage.asp”) and frame 2 (that should hold “someOtherASPpage.asp”).

when I click either of the two links I get taken directly to the “someASPpage.asp” page (which unfortunately covers the whole screen) and the passed argument is displayed. I want the “yes” or “no” string to be displayed in one of the two frames instead. The other frame in the frameset should be empty for now. How can I display a frameset and at the same time pass an argument to one of the frames?
