Thank you. That was the sub query I was looking for.

SELECT W.vendor,
      (SELECT count(C) As Checks
       FROM (SELECT V.vendor,
                    V.checkno AS C
             FROM VendorChecks V
             GROUP BY V.vendor, V.checkno)
       WHERE V.vendor=W.vendor) AS NumOfChecks,
       Sum(W.amt) AS SumOfamt
FROM VendorChecks AS W
GROUP BY W.vendor;

Slightly more complicated, but another way of doing the query.
