Saving a bean ignores certain fields

[affinity4]

Hello,

I have a custom module, and for the most part it works fine. But there are a couple fields that it refuses to save
to the database. The columns exist in the table, the variable exist in the module file, etc...

Any ideas on what it might be or where some other places to look are?

Sugar Version: Version 5.0.0b (Build 3150)
Sugar Edition: Professional
Category: Custom Module
OS: CentOS
PHP Version: 5.2.5
Database: mssql
Web Server: Apache 2

Thanks!
