Access97 SQL Syntax

I'm familiar with SQL but not with Access97 - some wierd syntax here!

I'm creating a Query that is to Delete records from a table depending on a non-key field in a second table.

I first tried an INNER JOIN


DELETE Activity_Preferences.*
FROM Activity_Preferences INNER JOIN Activity_Key
Activity_Preferences.Activity_Key=Activity_Key.Act ivity_Key AND Activity_Key.Complete=1;


which was initially accepted but then complained about the INNER JOIN after I went in a second time to 'fix' the error.

I've finally got the following syntax accepted:-


DELETE Activity_Preferences.*
FROM Activity_Preferences, Activity_Key
WHERE Activity_Preferences.Activity_Key=Activity_Key.Act ivity_Key AND Activity_Key.Complete=1;


But when executed still gets the following error (same as for the INNER JOIN):-

'Operation must use an updatable query'.

What else is needed?
