DSum expression

• Question

• I have a table for bankpayments, and one for creditor invoices. My Dsum expression is. DSum("[icsexcvat]","q06InvCrdsub","[Cmbent_Id]=" & [CmbentID])+DSum("[bpsexclvat]","q06BnkPmtSub","[CmbEntID]=" & [VehID]).

When there is an amount in each of the two fields, i.e. icsexcvat and bpsexclvat it calculates like I want it to. When either of the queries does not have a transaction it shows a "null" value. Even when I add Nz in front of the Dsum it returns a zero while it shouldnt when only one table has a transaction with the applicable reference.

My business buy cars. We may buy the car on credit but buy additions cash. As I said when both tables have at least one transaction the expression returns correct. When either of the two tables have no transaction against the same car it gives "null" or Zero. But one table have an amount. What should I do to calculate the one amount plus no transaction in the other table?

Thank you.

• Have you tried using Nz on both expressions?

Val(Nz(DSum("[icsexcvat]","q06InvCrdsub","[Cmbent_Id]=" & [CmbentID]),0))+Val(Nz(DSum("[bpsexclvat]","q06BnkPmtSub","[CmbEntID]=" & [VehID]),0))

• Do the fields balance and LdgAccNo occur in the Union001 query?

• I have a Union query 6500 records so far. Need to get a report from that. Tried expressions in a query.   Balance: +DSum("[balance]","Union001","[LdgAccNo]=" & [LdgAccNo])  and     Balance: Val(Nz(dsum("[balance]","Union001","[LdgAccNo]=" & [LdgAccNo]),0)). It continue to return #Error.   What could be my dumb moment?
