Hello. I have a program with a simple macro I am trying to make. Here is the macro right now, it works fine as is: (I have highlighted in bold what I would like to change)

Sub RequiredDate()
Dim rizange, rizaange, a_range, b_range, As Range
Set rizange = Range("H2:H8")
Set rizaange = Range("I2:I8")
For Each a_range In rizange
If a_range <> "" Then
Range("j" & a_range.Row).Select
ActiveCell.Formula = "=E2+10"
End If
Next

For Each b_range In rizaange
If b_range <> "" Then
Range("j" & b_range.Row).Select
ActiveCell.Formula = "=E2+15"
End If
Next
End Sub


I would like to change the cell formula part of the macro. Instead of all of them being E2 plus a number, I would like it to be E2, then E3, then E4, etc etc. But when I try to replace what I have with something like:
="("e" & b_range.Row)+15" it gives me an error. Is there a way that I can fix this?

Thanks for your help.
