problems with urlencoding

Hi, I try to send the content of a variable about the url to the next php-page. The content of the variable is: Client like '%4022720893%' I have tried urlencode and urldecode, but this does not work If I put this variable to an url, I got always Client like '@22720893%' (depending from the number after the first %), I also have tried to mask with slashes and stripslashes. But this does also not work. Who can help and has the best way to send this content thru an url best regards christian
