How to use 'Count' in Access for a field of type string

Dear All,

I have a table with the following fields.  I'm trying to count the number of times the same string appears in ItemID, the same string in ModelID for each LocationID.

ID (Number)
ItemID (String)
LocationID (Number)
ModelID (String)

I've tried:

SELECT Count([Table1].ItemID) AS ItemCount, Count([Table1].ModelID) AS ModelCount, [Table1].LocationID
FROM 
(SELECT DISTINCT [Table1].LocationID FROM  [Table1] );

Select allOpen in new window

The error states Query does not include LocationID as part of Aggregate function.  

Thanks
