Hallo everybody!

I´ve a vba code now that can generate combinations in excel but when it will com to the end of the rows, that means 65500(or something like that), I have built in code that order it to continue on another worksheet and it works but something is wrong. In the first worksheet it writes all combinations OK but on the next worksheet it do not work, what is wrong?
Do any body can help with sloving this problem?
Here is the code:

Sub aa()
Dim i, j, k, l, m, n, o, rw, summ, summ133, dif

rw = 1

For i = 1 To 19

For j = i + 1 To 24

For k = j + 1 To 26

For l = k + 1 To 30

For m = l + 1 To 33

For n = m + 1 To 34

For o = n + 1 To 35

summ = i + j + k + l + m + n + o

dif = o - i

If ((summ > 98) And (summ < 106) And (dif > 13)) Then

Cells(rw, 1) = i

Cells(rw, 2) = j

Cells(rw, 3) = k

Cells(rw, 4) = l

Cells(rw, 5) = m

Cells(rw, 6) = n

Cells(rw, 7) = o

rw = rw + 1

End If

If ((summ133 = 133) And (dif > 13)) Then

Worksheets("Blad2").Cells(rw, 1) = i

Worksheets("Blad2").Cells(rw, 1) = j

Worksheets("Blad2").Cells(rw, 1) = k

Worksheets("Blad2").Cells(rw, 1) = l

Worksheets("Blad2").Cells(rw, 1) = m

Worksheets("Blad2").Cells(rw, 1) = n

Worksheets("Blad2").Cells(rw, 1) = o

rw = rw + 1

End If

Next o

Next n

Next m

Next l

Next k

Next j

Next i

End Sub
