Tell program to omit a certain tab

Sub CopyFromWorksheets()
    Dim wrk As Workbook 'Workbook object - Always good to work with object variables
    Dim sht As Worksheet 'Object for handling worksheets in loop

A friend of mine made me this code and it basically combines all tabs into 1 "Master" tab. I need to modified it to omit the first tab. Its always named "Delivery Schedule". Can someone help me with this? I'm still a noob when it comes to programing.

hi, try to change this:

 Set rng = sht.Range(sht.Cells(2, 1), sht.Cells(65536, 1).End(xlUp).Resize(, colCount))
         'Put data into the Master worksheet
        trg.Cells(65536, 1).End(xlUp).Offset(1).Resize(rng.Rows.Count, rng.Columns.Count).Value = rng.Value

to this:

If sht.Name <> "Delivery Schedule" Then
        Set rng = sht.Range(sht.Cells(2, 1), sht.Cells(65536, 1).End(xlUp).Resize(, colCount))
         'Put data into the Master worksheet
        trg.Cells(65536, 1).End(xlUp).Offset(1).Resize(rng.Rows.Count, rng.Columns.Count).Value = rng.Value
        End If
