Changing the properties of a word document

I want to change the property title in a word document I am generating via VBA and I have been looking out on the web for some examples.

I found the following code but it doesn't seem to work.

.ActiveDocument.BuiltInDocumentProperties(wdPropertyTitle) = ""

Is this the correct method? If not could you point me in the right direction?

Thanks,
DL

Edit: I'm using office 2003

are you calling this code from within the word document or from an external app?

can you post your code and what the error is?

The whole document of code is too big to post here, I just need to know the correct method to change the properties of of a word document using vba.

Using the code above calling it from an external app, the error I get is "invalid procedure call or arguement"

Thanks for the help. I am not using vb.net

Your talking about this property?

VB Code:

Documents(1).BuiltInDocumentProperties(wdPropertyTitle).Value = "Test"
'wdPropertyTitle = 1
