I have a task to add a comment in a sumtotal by month to show the items involved and the amount. I Want to simplify the works because Ido it by monthly and every job (over 20 jobs)!
I found solutions for a single cell.
I need to add related cell values to one comment for the month.

Option Explicit
Sub CreateComment()
Dim rng As Range
Dim cel As Range
Dim myColumn, myRow As Integer
Set rng = Selection
myColumn = ActiveCell.Column
myRow = ActiveCell.Row
For Each cel In rng
If cel.Value <> "" Then
Range("myColumn" & "1").AddComment [Cell("myRow", "1")).Value & " -$" & Cell("myRow","myColumn")_.value]
End If
Next
End Sub
