Using VB To Password Protect From User Form

I have coded a user form to automatically unprotect a sheet, then protect it with a password after data is entered from the User Form. Works great. However, after it is protected through the User Form script, I cannot unprotect the sheet to edit it. It will not recognize that it is the correct password, although it is.

Private Sub cmdOK_Click()
Dim NextRow As Long
NextRow = Application.WorksheetFunction.CountA(Range("b:b")) + 2
Cells(NextRow, 2) = txtAddProvider.Text
ActiveSheet.Unprotect Password = "stats@fwh"
Range("B3:B21").Select
Selection.AutoFilter
Selection.AutoFilter
ActiveWorkbook.Worksheets("Lists").AutoFilter.Sort.SortFields.Clear
ActiveWorkbook.Worksheets("Lists").AutoFilter.Sort.SortFields.Add Key:=Range( _
"B3:B21"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:= _
xlSortNormal
With ActiveWorkbook.Worksheets("Lists").AutoFilter.Sort
.Header = xlYes
.MatchCase = False
.Orientation = xlTopToBottom
.SortMethod = xlPinYin
.Apply
End With
ActiveSheet.Protect Password = "stats@fwh"
End Sub
