This is an addendum to my previous question which was answered. The code below works when I split a concatenated string from a field in Table A and append the records to a Field in Table B. Now I have added a second concatenated field from Table A, that I need to append concurrently into a different field from the same record of Table B.

So basically:

Table A
Record  1:
Field 1 = 10, 20, 30, 40
Field 2 = 50, 60, 70, 80

becomes . .  .

Table B
Record 1: Field 1 = 10  Field 2 = 50
Record 2: Field 1 = 20  Field 2 = 60
Record 3: Field 1 = 30  Field 2 = 70
Record 4: Field 1 = 40  Field 2 = 80

The code below achieves the original desired result in appending Field 1 from Table A into separate records in Table B. I have tried different coding combinations to include the second split but nothing has worked. Thanks for your help again.

Public Sub SplitSetReps()
Dim rsIn As DAO.Recordset
Dim rsOut As DAO.Recordset
Dim intX As Integer

Set rsIn = CurrentDb.OpenRecordset("SELECT * Table A WHERE ID =  " & Forms!frmMainDetail!StrID, dbOpenDynaset)
Set rsOut = CurrentDb.OpenRecordset("Table B", dbOpenDynaset)

Do While Not rsIn.EOF
    If Not IsNull(rsIn!Reps) Then
        astrNames = Split(rsIn![Reps], ",")
    End If

    For i = 0 To UBound(astrNames)
        rsOut.AddNew
        rsOut![SetsRep] = astrNames(i)
        rsOut![SetsRepID] = rsIn!StrID

        rsOut.Update
    Next
    rsIn.MoveNext
Loop

End Sub

Add after string:
astrNames = Split(rsIn![Reps], ",")
this string:
astrNames1 = Split(rsIn![Reps1], ",")
Reps1 - Field 2 name in Table A
and after string
 rsOut![SetsRep] = astrNames(i)
this:
 rsOut![SetsRep1] = astrNames1(i)
SetsRep1 - Field 2 name in Table B

Thanks als315. I have tried that solution and it works for the most part. However, at times the additional field in (SetsRep1) may be a Null value. When it is, I get a Run Time Error '9'; Subscript Out of Range message. I have tried several If IsNull Statements to alleviate the problem, again to no avail. Thanks again if you can assist me further.

Let me retract that somewhat. It appears as if the error occurs when the strings do not match with the same number of array components (i). so if Field one is 10, 15, 20, 25, and Field 2 is 35, 45, and 65, I generate the error. I'll keep trying to narrow down this error. Thanks.

OK. You can add this condition:
if UBound(astrNames1) > i then
 rsOut![SetsRep1] = astrNames1(i)
end if

Ok, we're getting there. When I insert your code into the condition, it works with the exception of the last value in the array of SetsRep1. So if the string is 10, 15, 20, 25 the field values in Table B are 10, 15, 20. The last value (25) is a null field. The original array (astrNames) contains all the values of the string. I'll keep playing with the condition statement. Thanks.

Here is how I got it to work. I used the >= in the condition statement, and everything copied over correctly. Thank you for your assistance. I will continue to test all of the conditions, but will definitely award you the points. I appreciate it.

if UBound(astrNames1) >= i then
 rsOut![SetsRep1] = astrNames1(i)
end if
