Ambiguous outer join in MS Access

Trying to create an outer join on two other joined tables when recieving this error - I just dont see how to create two separate queries to make it work. Subqueries don't seem to work either, any help appreciated. I get errors for the below query, thanks.

SELECT
CardHeader.CardID, CardHeader.CardDescription, CardHeader.GloveSize,
CardHeader.GloveDescription, CardDetail.Bin, CardDetail.ItemID, Items.ItemDescription,
Items.VCatalogID, CardDetail.ChargeCode, CardDetail.Quantity, Items.Cost, CardColors.ColorID
FROM
((Items
INNER JOIN
(CardHeader INNER JOIN CardDetail ON CardHeader.CardID = CardDetail.CardID) ON Items.ItemID = CardDetail.ItemID)
LEFT JOIN
CardColors ON CardDetail.ItemID = CardColors.ItemID)
INNER JOIN
Colors ON CardColors.ColorID = Colors.ID
ORDER BY
CardHeader.CardID;


I tried the following which runs but asks for the following parameters (which it shouldnt)

CardHeader.ID, MainQry.CardID

SELECT
MainQry.ID, MainQry.CardDescription, MainQry.GloveSize,
MainQry.GloveDescription, MainQry.Bin, MainQry.ItemID,
MainQry.ItemDescription, MainQry.VCatalogID, MainQry.ChargeCode,
MainQry.Quantity, MainQry.Cost, SubQry.ColorID
FROM
(SELECT
CardHeader.ID, CardHeader.CardDescription, CardHeader.GloveSize,
CardHeader.GloveDescription, CardDetail.Bin,
CardDetail.ItemID, Items.ItemDescription, Items.VCatalogID,
CardDetail.ChargeCode, CardDetail.Quantity, Items.Cost
FROM
Items
INNER JOIN
(CardHeader
INNER JOIN
CardDetail ON CardHeader.CardID = CardDetail.CardID) ON Items.ItemID = CardDetail.ItemID
) AS MainQry
LEFT JOIN
(SELECT
CardColors.ItemID, CardColors.ColorID
FROM
CardColors
INNER JOIN
Colors ON CardColors.ColorID = Colors.ID) AS SubQry ON MainQry.ItemID = SubQry.ItemID
ORDER BY
MainQry.CardID;

Answer

The second SQL statement can be corrected by reference to the first statement and the error. The error is that both CardHeader.ID and MainQry.CardID are prompting for a parameter, which indicates that the inner statement should include CardHeader.CardID, rather than CardHeader.ID
