I have the following table that I import into excel... What I am needing to do is loop through the names (i.e. Emp1). For every instance of that employee, I need to copy columns C through F and paste in another worksheet. I would like for this to happen with every employee on the sheet.

Sub DiscrepFormReport()
    Dim cell As Range

    Range("A1").Select

    Application.ScreenUpdating = False

    'Range("A1") = Sheets("RawData").range("B2))

    For Each cell In Range("B2:B200")
        If cell <> "" Then
            Sheets("RawData").Range("C2:F2").Copy
            Sheets("DiscrepencyForm").Range("C2:F2").PasteSpecial Paste:=xlPasteValues
            ActiveCell.Offset(1, 0).Select
        End If
    Next cell

    Application.ScreenUpdating = True
End Sub

If I'm understanding the idea, you'd want something like:

Sub Example()
    Const STARTING_ROW As Long = 2
    Dim c As Long: c = STARTING_ROW

    Application.ScreenUpdating = False
    Application.Calculation = xlCalculationManual

    Dim cell As Range
    For Each cell In Sheets("RawData").Range("B2:B200").Cells
        If cell <> "" Then
            Sheets("DiscrepencyForm").Range("C:F").Rows(c).Value = cell.EntireRow.Columns(3).Resize(, 4).Value
            c = c   1
        End If
    Next
    
    Application.ScreenUpdating = True
    Application.Calculation = xlCalculationAutomatic
End Sub

You can avoid .Copy since you're specifying that you only want values. You can just directly assign the values on the range objects, which skips the use of the windows clipboard and saves a lot of time. No need for Select or Activecell. All we need is to use the cell loop element and a second index, c, to track the destination range on the other sheet.
