Find row number in For loop

I would like to grab the row number of a certain cell in a For loop, but I'm getting the 'Wrong number of arguments or invalid property assignment' error on the line: Cell.offset(1).Row = thisrow

Dim thisrow As Integer
    
        For Each cell In rngtest
            If cell.Value < linenumber And cell.Offset(1).Value > linenumber Then
                If cell.Value <> "" Then
                    cell.Offset(1).EntireRow.Select
                    Selection.Insert Shift:=xlDown
                    cell.Offset(1).Value = linenumber
                    cell.Offset(1).Row = thisrow
                End If
            End If
        Next

This seems like an easy fix, but I can't figure it out

Thanks,
Chad
