Help on handlin calendar day click ?????

[Guest]

Dear all

I have a set of 3 frames named " Banner", "main" and "Content"
I have a calendar control which is place on a page named "Calendar.aspx",
set as the source of frameSet named "Content".
If I click on a calendar day, I need to transfert user to a page name
Day.aspx.

Actually the page is displayed on the same framSet as my calendar control .

How can I display my Day.aspx page on the Framset named "main" ?

thanks for your help
regards
