In access I have a table and within a QUery I want to check to see if a field is not Null and if so multiple 2 x 25).

So if [LarRecvDate] is not null then write 2 *25.

What would the syntax in the query be?

You're going to need to be a bit more specific on exactly what you're trying to do in order for us to help you.

ok in the row from the table I want to evaluate.

A field called  "LarRecved" can be null or not null.
if the field is not null I want to calculate using an expression in the query.

So if LarRecved is not null multiply 2 *25.

Does this help?

select [LarRecved], IIF([LarRecved] & ""<>"",2*25,Null)
from tableX


why not just use 50 instead of 2 * 25


post sample values from field LarRecved  and the result you expect to get when LarRecved  is NOT null and when LarRecved is NULL

So either there is a date in LARRECVDATE or its empty


select [LARRECVDATE], IIF([LARRECVDATE] & ""<>"",2*25,Null)


I could just enter 50 that is true.  When I entered the above syntax it is giving me an error .

I am missing something?

you have to include the "From TableName"


select [LARRECVDATE], IIF([LARRECVDATE] & ""<>"",2*25,Null)
From TableName

copy this as the one COMPLETE query

select [LARRECVDATE], IIF([LARRECVDATE] & ""<>"",1*25,Null) as Owed
from tblclaim1

OR post the whole query you are using

Here you go


SELECT tblClaim1.ClaimID, tblClaim1.ClaimNo, tblClaim1.Claimant, tblClaim1.LARRECVDATE, tblEorRecvd.EORRecDate
FROM tblClaim1 INNER JOIN tblEorRecvd ON tblClaim1.ClaimID = tblEorRecvd.ClaimID
select [LARRECVDATE], IIF([LARRECVDATE] & ""<>"",1*25,Null) as Owed
from tblclaim1;

SELECT tblClaim1.ClaimID, tblClaim1.ClaimNo, tblClaim1.Claimant, tblClaim1.LARRECVDATE, tblEorRecvd.EORRecDate, IIF(tblClaim1.[LARRECVDATE] & ""<>"",1*25,Null) as Owed
