I am trying to create vba code to sort multiple sheets by clicking on a
command button. I got it to sort the first page correctly, (the page the
button is on), but I'm having trouble getting it to sort other pages. I get
this error: "Method 'Range' of object '_Worksheet' failed."

On each sheet, I have three columns with headers: first name (columnA), last
name(columnB), and number (columnC).

Here is the code I have so far. I have one sub to sort the sheets
alphabetically, and one to sort by number:

Option Explicit
Private Sub cmdSortAlpha_Click()
Worksheets("Sheet1").Select
Worksheets("Sheet1").Range("A2:C50").Sort _
Key1:=Range("A2:A50"), _
Order1:=xlAscending, _
Key2:=Range("B2:B50"), _
Order2:=xlAscending, _
Header:=xlNo
Worksheets("Sheet2").Select
Worksheets("Sheet2").Range("A2:C50").Sort _
Key1:=Range("A2:A50"), _
Order1:=xlAscending, _
Key2:=Range("B2:B50"), _
Order2:=xlAscending, _
Header:=xlNo
End Sub

Private Sub cmdSortNumber_Click()
Worksheets("Sheet1").Select
Worksheets("Sheet1").Range("A2:C50").Sort _
Key1:=Range("C2:C50"), _
Order1:=xlAscending, _
Header:=xlNo
Worksheets("Sheet2").Select
Worksheets("Sheet2").Range("A2:C50").Sort _
Key1:=Range("C2:C50"), _
Order1:=xlAscending, _
Header:=xlNo
End Sub
