NAT problem on 2 ASA's

Ok this config was working for a while and then just stopped and I'm at a loss with this one. I have two ASA 5505's connected together. ASA1 is directly connected the internet via DHCP and has an Outside, Inside, and DMZ vlan. ASA2 is connected to ASA1 and only has an Inside and Outside vlan. ASA2's Outside is connected to ASA1's DMZ and from there I'm trying to NAT to the Outside vlan. From ASA2, I can ping the Inside interface but not the Outside of ASA2 or the DMZ of ASA1. I used to be able to ping the DMZ of ASA1 from an Inside host on ASA2 but this is no longer the case. On ASA1 from the ASDM I can see that ICMP packets are reaching ASA1 on the DMZ, but I cannot connect to the Internet. Essentially what I'm trying to do here is connect ASA2 to ASA1 as if ASA1 was the ISP. ASA2 is then hosting VM's so that I can test my configurations. I have attached a diagram and my two configs to try to make this clear as possible. Any help is appreciated ;-)

So my understanding in you are using ASA1's DMZ as the outside interface for ASA2?  I may be missing something here, but it doesn't look like you have annat rule on ASA2 that map external to internal

SuperTaco..... SuperTaco..... Where do I begin...... LOL just kidding ;-) Ok here is the situation. I'm learning these ASA's and only configed ASA2 from the CLI. I must have screwed it up. I took my laptop and configured ASA2 via the ASDM and did static mapping and now it works perfect. Thanks for the suggestion. I have to learn the CLI better... but for now I just needed this to work. Thank you!!!
