Using a Do Until Loop to search for and modify data in a table

[tehgreatmg]

Here is my code:

    Dim db As DAO.Database
    Dim rs1 As DAO.Recordset

    Set db = CurrentDb()
    Set rs1 = db.OpenRecordset("CartUse")
    rs1.MoveFirst
  
    Do Until rs1.EOF
        If rs1.Fields(ID) = Val(ID) Then
            NumOrdTotal = Val(rs1.Fields(varLongMonth)) + Val(varNumOrd)
            txttest2 = Val(NumOrdTotal)
            rs1.Edit
            rs1.Fields(varLongMonth) = Val(NumOrdTotal)
            rs1.Update
        End If
        rs1.MoveNext
    Loop

  rs1.Close
  Set rs1 = Nothing
  Set db = Nothing

What I am needing this to do is search through my table to match the value of the Field "ID" to the value of (ID), which is a txtBox on a form bound to another table. If it matches these two values then I need it to do the calculations in the If statement. It works for the first record, but will not work for any of the other records. Both ID fields are autonumber fields.

Not sure why you want this, as normally this is done by using a query.
The problem with your code is the fact that you need to use:
If rs1.Fields("ID" ) = Val(Me.ID) Then
The " is needed to refer to the field value in the recordset, alternatively you could use:
If rs1!ID = Val(Me.ID) Then
When referring to form fields it's better to use the Me infront of the name.
