I have not used cookie.lib myself, so now I'm guessing ..

Have you included the cookie in the page you send to the browser ?

print "Content-type: text/html\n";
&SetCookies('name',"$name",'email',"$email");
print "\n";

The symptoms you describe sounds alot like either the above or that the SetCookieExpDate call didn't work.

Or perhaps the order is essential, aka you need to call SetCookies after SetCookieExpDate ?
