Choice between "Compile Error" and "Error 91 - Object Variable Not Defined"

My problem has changed to getting a "Compile Error" on this line after adding the "Set" statement:

"Set qstart = Worksheets"

and without "Set", I get "Error 91 Object Variable or With Block not defined". Been on this one for better part of two days now.

If not a solution, I could use some suggestions

Sub QIND()

    If Range("M7").Value = "True" Then         ' M7 is a checkbox reference cell in "Checklist"
        Call HideQIND                       ' To hide questions in FielBook
        Worksheets("Checklist").Activate
    ElseIf Range("M7").Value = "False" Then
        Call UnHideQIND                     ' To unhide questions in FieldBook
        Worksheets("Checklist").Activate
    End If
End Sub

Sub HideQIND()

Dim qstart As Long 'Integer
Dim qend As Long 'Integer

    Worksheets("FieldBook").Activate

    Set qstart = Worksheets("FieldBook").Range("A:A").Find(what:="IND", after:=Range("A1"), searchdirection:=xlNext).Row
    qend = Range("A:A").Find(what:="IND", after:=Range("A1"), searchdirection:=xlPrevious).Row 'left this statement alone until my error goes away or at least shifts

    Worksheets("FieldBook").Rows("qstart:qend").EntireRow.Hidden = False
 End Sub

Sub UnHideQIND()

Dim qstart As Integer 'Range ' Long 'Integer
Dim qend As Integer 'Range 'Long 'Integer

    Worksheets("FieldBook").Activate
      
    Set qstart = Worksheets("FieldBook").Range("A:A").Find(what:="IND", after:=Range("A1"), searchdirection:=xlNext).Row
    qend = Range("A:A").Find(what:="IND", after:=Range("A1"), searchdirection:=xlPrevious).Row

    Worksheets("FieldBook").Rows("qstart:qend").EntireRow.Hidden = True
End Sub
