Deleting a row in a sheet when 2 cells in 2 different sheets are the same

Question

This macro should compare cells in 2 different rows in 2 worksheets in the same workbook. When the value of the cells matches the row of the cell with the same value in a third worksheet same workbook should get deleted.

In the sheets that get compared are formulas but not in the sheet were the rows should be deleted.

The Problem is that it does not delete the cells in the third sheet. I inserted pieces of code that suggest me that the comparison works. But the code seems to randomly delete stuff.

I tried solutions from the following (and some others were i dont have the links anymore) links:

    s2.Cells(i, 6).EntireRow.Delete
    s1.Cells(i, 9).Value = s3.Cells(i, 5).Value

Answer 1

In case of using the code:

Dim i As Long
With Workbooks("Book1").Worksheets("Sheet1")
    For i = 1 To 4
        If IsEmpty(.Cells(i, 1)) Then .Rows(i).Delete
    Next i
End With

You will miss some rows. For example, if the code deletes row 3, then row 4 becomes row 3. However, variable i will change to 4. So, in this case the code will miss one row and check another, which wasn't in range previously.

In your case you should use this

For i = Sht1LastRow To 15 Step -1
