Session Variables With Spaces

I have two php pages using session variables. One redirects to itself after refreshing the variables, and the other redirects to a second php page, retrieves some values into the session variables, and then returns to the first page. The one that redirects to itself works fine. The one that calls an intermediate page truncates session variables at the first space when returning back to the original page. Any thoughts on what causes this would be much appreciated. Eric Pankoke Point Of Light Software "Lighting The Path To Glory" http://www.polsoftware.com/
