I always believe it's safer to use a double click event
When you double click on a cell in column M this row of data will be copied to sheet named Completed Orders
And the row will then be deleted from original sheet.
This is an auto sheet event script
Your Workbook must be Macro enabled
To install this code:
Right-click on the sheet tab
Select View Code from the pop-up context menu
Paste the code in the VBA edit window
Put this script in the sheet named Tracker
Code:
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
'Modified 6/4/18 7:00 AM EDT
If Not Intersect(Target, Range("M:M")) Is Nothing Then
If Target.Cells.Count > 1 Or IsEmpty(Target) Then Exit Sub
Cancel = True
Dim r As Long
Dim Lastrow As Long
Lastrow = Sheets("Completed Orders").Cells(Rows.Count, "M").End(xlUp).Row + 1
r = Target.Row
Rows(r).Copy Sheets("Completed Orders").Rows(Lastrow)
Rows(r).Delete
End If
End Sub
