Creating a site-to-site VPN with PIX 501 and ASA 5505

I'm trying to create a VPN between a PIX 501 and the ASA 5505...relevant config below for the PIX...when I try to create a matching config on the ASA side, I get a message that says "Ignoring msg to mark SA with specified coordinates <outside_map, 20> dead".   I've redone this on the ASA side 10 times today both by hand and by ADSM, and keep getting the same message.  Can someone help me with the correct VPN config for the ASA?  Thanks!

Thanks, turns out it was a routing issue instead of a VPN configuration issue.
