Displaying a SUM value in a textbox using VBA

Hi,

I have a textbox on a form (txtCurrentBill) where I would like to display the user's current bill.

I have globally declared the the unique Account number (lngBarNo) based on the logged in user.

I would like to reference the Transactions table (tblTransactions) and display the Sum of the Amount field in tblTransactions for the given account number and where the Invoiced field = No

I tried using a SQL statement but this didn't work too well :(

Any idea what's wrong with my code or is there a better/cleaner way to do this?

Thanks in advance


Dim mydb As Database, rsEnq As Recordset

    Dim sqlCurrentBill As String

 

    sqlCurrentBill = "SELECT tblTransactions.BarNo, Sum(tblTransactions.Amount) AS SumOfAmount, tblTransactions.Invoiced " & vbCrLf & _

    "FROM tblTransactions " & vbCrLf & _

    "GROUP BY tblTransactions.BarNo, tblTransactions.Invoiced " & vbCrLf & _

    "HAVING (((tblTransactions.BarNo)= '" & lngBarNo & "') AND ((tblTransactions.Invoiced)=""No""));"

 

    ' Create database.

    Set mydb = DBEngine.Workspaces(0).Databases(0)

 

    ' Create dynaset.

    Set rsEnq = mydb.OpenRecordset(sqlCurrentBill, DB_OPEN_SNAPSHOT)

 

    ' Populate text box controls.

    On Error Resume Next

    Me![txtCurrentBill].Value = rsEnq.Fields("[SumOfAmount]").Value

 

    mydb.Close

Me![txtCurrentBill]=DSum("Amount","tblTransactions", "BarNo= " & lngBarNo & " AND Invoiced='No')

This assumes lngBarNo is a number.

    Dim curX As Currency

    On Error Resume Next

    curX = DSum("[Amount]", "tblTransactions", _

    "[BarNo] = " & lngBarNo & " AND [Invoiced] = 'No'")

    Me.txtCurrentBill.Value = curX
