Every time i run the macro it has different values, need help please

[matrix100]

Hello. With my small knowledge of programming i write an excel macro and every time i run it has different values. The code I believe is correct and it is making what i want it to do. If I run the macro in Step by Step i believe it makes the corect values. Can anyone help me please? Thank you so much

Your problem is a timing issue, the clue is the fact you get the correct answer when you step through it. You are looping through picking up cells from the worksheet doing some calculations , then writing cells back to the worksheet doing some more ca lculations then picking up the same cells again and doing more calculations, the trouble is that sometimes when you pick the cell up for the second time it hasn't updated from when you wrote it. The way to solve this is to load all of the cells you are using into a variant array and do the whole calculation in VBA and only write back to the spreadsheet at the end. Note this is a much faster way of doing the calculation anyway , you should always do yor calculation like this. So try this code. I get the same answer every time with this code:

Sub filanoua2()
Dim matrix(20) As Double
Dim matrixindicator As Integer
Dim sumamatrice As Double
Dim sumaintermediara As Double
matrixindicator = 1
Dim tester As Integer
Dim Wrange As Variant
Worksheets("filenoua").Select
Wrange = Worksheets("filenoua").Range(Cells(1, 1), Cells(400, 25))
tester = 0
For q = 1 To 40
    For w = 1 To 10
        If Wrange((q - 1) * 10 + w, 6) = "" Then Exit Sub
        Wrange((q - 1) * 10 + w, 13) = (Wrange((q - 1) * 10 + 1, 22)) / 10 / (Wrange((q - 1) * 10 + w, 6) - 1)   ' poata sa fie -1 sau fara
        If Wrange((q - 1) * 10 + w, 3) = Wrange((q - 1) * 10 + w, 4) Then Wrange((q - 1) * 10 + w, 20) = Wrange((q - 1) * 10 + w, 6) * Wrange((q - 1) * 10 + w, 13) - Wrange((q - 1) * 10 + w, 13)
        If Wrange((q - 1) * 10 + w, 3) <> Wrange((q - 1) * 10 + w, 4) Then Wrange((q - 1) * 10 + w, 20) = -1 * Wrange((q - 1) * 10 + w, 13)
        sumaintermediara = suma((q - 1) * 10 + 1, w - 1)
        If sumaintermediara >= Abs(sumamatrice) And w <> 0 And tester = 0 Then
            Wrange((q - 1) * 10 + 1, 22) = Wrange(1, 22)
            matrixindicator = 1
            sumamatrice = 0
            tester = 1
        End If
    Next w
    If tester = 0 Then sumaintermediara = 0
    Wrange(q * 10 + 1, 22) = suma((q - 1) * 10 + 1, (q - 1) * 10 + 10)
    If Wrange(q * 10 + 1, 22) + sumaintermediara > Abs(sumamatrice) Then
        Wrange(q * 10 + 1, 23) = Wrange(q * 10 + 1, 22)
        Wrange(q * 10 + 1, 22) = Wrange(1, 22)
        
        matrixindicator = 1
        sumamatrice = 0
        tester = 0
        sumaintermediara = 0
    End If
    If Wrange(q * 10 + 1, 22) + sumaintermediara < Abs(sumamatrice) Then
    
        matrix(matrixindicator) = Wrange(q * 10 + 1, 22)
        matrixindicator = matrixindicator + 1
        sumamatrice = 0
        For bn = 1 To matrixindicator - 1
            sumamatrice = sumamatrice + matrix(bn)
        Next bn
        
        Wrange(q * 10 + 1, 23) = Wrange(q * 10 + 1, 22)
        Wrange(q * 10 + 1, 22) = -10 * sumamatrice
        tester = 0
        sumaintermediara = 0
    End If
Next q
Worksheets("filenoua").Range(Cells(1, 1), Cells(400, 25)) = Wrange


End Sub
