Custom fields not shown in database

[glenn]

Hi,

I need to access data in MS Project to apply it to a web application that
displays Project information on the internet. I can access data from either
a MS Access database or from a XML file. I could use MS Project Server but I
am doing very specialized stuff and am therefore attempting to not go that
route. Some of the data I need to get at is custom fields that I created in
Project in my case for custom cost fields.

I have saved a project as an Access Database. If I open the database file
in Access, I do not see the value for the custom field. On the other hand,
if I save
the file as a XML file and then open the XML file, I do see the custom cost
field.

I do not need to use XML, despite its many advantages, and would prefer to
just access a database file directly.

Can anyone tell me why my custom fields are not showing up in a MS Access
file?

Thanks for your help...
