After Submit Script and To Be Generated SO #s

Hi all,

I have a script that was originally (and, I believe, incorrectly) going to be a Before Submit User Event script. All it does it look at some fields on the Sales Order and either mark a checkbox or not, based on some criteria (eventually these orders will be automatically approved, but we're new to scripting and starting slow).

The script is to run on both create and edit. I was having a problem where the script couldn't get the SO number or the credit card security checks on Before Submit, so I moved it to being an After Submit User Even Script instead. However, it still is saying that the orderstatus is 'null' (it should be 'A' for pending approval), the AVS and CSC checks are 'null' (they should generally be Y or N), and that the tranid is "To Be Generated", rather than a number beginning with SO.
