Syntax Error with DSum Statement

[RodShinall]

I am trying to build a personal check register application and I need to write a DSum statement with two criteria as the control source of an unbound text box control which give me a running balance and I can't get the syntax correct. TransactionAmount and TransactionNumber are both number fields and Account is short text. I've tried replacing the double quotes with single quotes but still get an invalid syntax error. Any help would be greatly appreciated.

txtBalance.ControlSource = "=DSum("[TransactionAmount]","tblAccountRegister","[TransactionNumber] <= " & txtTransactionNumber.Value & " AND [Account] = '" & mstrAccountNumber & "')"

are the Transaction Number and Account Numbers really numbers or are they numbers stored in a text field. If text you need single quotes delimiter around the value.

try:

txtBalance.ControlSource = "=DSum(""[TransactionAmount]"",""tblAccountRegister"",""[TransactionNumber] <= " & txtTransactionNumber.Value & " AND [Account] = '" & mstrAccountNumber & "'"")"

TransactionNumber is a number stored in a Number field. Account is a text string stored in a text field.

I had to play with it to get it rigth

Public Sub test()
  Dim str As String
  Dim txttransactionnumber As Long
  txttransactionnumber = 1234
  Dim mstrAccountNumber As String
  mstrAccountNumber = "abcd"
  str = "=DSum(""[TransactionAmount]"",""tblAccountRegister"",""[TransactionNumber] <= " & txttransactionnumber & " And [Account] = '" & mstrAccountNumber & "')"
  Debug.Print str
End Sub

=DSum("[TransactionAmount]","tblAccountRegister","[TransactionNumber] <= 1234 And [Account] = 'abcd')

why are you assigning the controlsource in code? why not just include it in design view

=DSum("[TransactionAmount]","tblAccountRegister","[TransactionNumber] <= " & txtTransactionNumber & " AND [Account] = '" & mstrAccountNumber & "'")

That was my next question because doing that in code is kind of a PITA. Also you could simply set the value

try:

txtBalance.ControlSource = "=DSum(""[TransactionAmount]"",""tblAccountRegister"",""[TransactionNumber] <= " & txtTransactionNumber.Value & " AND [Account] = '" & mstrAccountNumber & "'"")"

Thanks for your reply. Your code does not produce an error but does not give me the running total.

not give me the running total.

you need to do it in a Query.

Thanks for your reply. I'll try this.

You're right, I did this with a query and it works perfectly. Thank you.
