access query error overflow

I have attached a query giving the Overflow error when I attempt to run.  I have changed datatype to Double for the number fields, have checked all items are not Null or zero and when I remove the criteria <0.35, the query runs fine.  I want this query to show items less than 35%.

Have you tried adding the calculated field to the underlying query?  For example, add to qryClaimComparisonYTD the column
([Free]+[Reduced])/[FRNtotal] AS FRPercentage
and then set the criteria in your current query to
WHERE FRPercentage < 0.35

Your problem is obviously where FRNTotal is either NULL, zero, or extemely small.

You might want to consider something like:

SELECT qryClaimComparisonYTD.[Center Name]
, qryClaimComparisonYTD.ClaimDate
, qryClaimComparisonYTD.Free
, qryClaimComparisonYTD.Reduced
, qryClaimComparisonYTD.[Non-Needy]
, qryClaimComparisonYTD.FRNTotal
, IIF(NZ([FRNTOTAL], 0) < .0001, 100, ([Free]+[Reduced])/[FRNtotal]) AS FRPercentage
FROM qryClaimComparisonYTD
WHERE (((([Free]+[Reduced])/[FRNtotal])<0.35));

This would give you a percentage of 100 for those where [FRNTotal] is NULL or zero.

First, do not attach simple code as a document.
Then protect against Null values of FRNtotal:

SELECT
    qryClaimComparisonYTD.[Center Name],
    qryClaimComparisonYTD.ClaimDate,
    qryClaimComparisonYTD.Free,
    qryClaimComparisonYTD.Reduced,
    qryClaimComparisonYTD.[Non-Needy],
    qryClaimComparisonYTD.FRNTotal,
    IIf([FRNtotal] Is Null, 1, ([Free]+[Reduced])/Nz([FRNtotal],1)) AS FRPercentage
FROM
    qryClaimComparisonYTD
WHERE
    IIf([FRNtotal] Is Null, 1, ([Free]+[Reduced])/Nz([FRNtotal],1)) < 0.35;

Have tried all three suggestions above, however still receiving the overflow error.  
FYI....... If I remove the criteria <0.35, the query runs fine and shows all of  the FRPercentage.  Once the criteria is entered in the query... it overflows.

Check out the function provided in response to this similar question.Then you would modify your query like:

SELECT qryClaimComparisonYTD.[Center Name]
, qryClaimComparisonYTD.ClaimDate
, qryClaimComparisonYTD.Free
, qryClaimComparisonYTD.Reduced
, qryClaimComparisonYTD.[Non-Needy]
, qryClaimComparisonYTD.FRNTotal
, AvoidError(([Free]+[Reduced])/[FRNtotal], 2) AS FRPercentage
FROM qryClaimComparisonYTD

YOu might have to play with the 2nd AvoidError argument.

The function provided has not determined the error for this query.  Perhaps I am not using properly.  Can you offer more assistance?

Try this:

SELECT
     qryClaimComparisonYTD.[Center Name],
     qryClaimComparisonYTD.ClaimDate,
     qryClaimComparisonYTD.Free,
     qryClaimComparisonYTD.Reduced,
     qryClaimComparisonYTD.[Non-Needy],
     qryClaimComparisonYTD.FRNTotal,
     IIf([FRNtotal] Is Null, 1, ([Free]+[Reduced])/Nz([FRNtotal],1)) AS FRPercentage
 FROM
     qryClaimComparisonYTD
 WHERE
     CCur(IIf([FRNtotal] Is Null, 1, ([Free]+[Reduced])/Nz([FRNtotal],1))) < CCur(0.35);

I'm surprised that the AvoidError() function is not identifying the problem.

I think you also need to test for [FRNTotal] = 0 and for the numerator (sum of two fields) also being NULL.  Try this, it will not actually compute the percentage, but should help you identify the record(s) causing the problem.

SELECT qryClaimComparisonYTD.[Center Name]
, qryClaimComparisonYTD.ClaimDate
, qryClaimComparisonYTD.Free
, qryClaimComparisonYTD.Reduced
, qryClaimComparisonYTD.[Non-Needy]
, qryClaimComparisonYTD.FRNTotal
, iif(IsNull([Free] + [Reduced]), True, False) as Numerator
, iif(IsNull([FRNTotal]), True, False) as DenomNull
, iif(NZ([FRNTotal], -1) = 0, True, False) as DenomZero
FROM qryClaimComparisonYTD
