ToggleButtons For Hide And Show Rows

I have a worksheet with 4 sections of rows. Each section I call Goal 1 - Goal 4. I want to show each section and hide the other sections by clicking on a button. I have used a column, P, to denote which Goal a row belongs to by entering 1, 2, 3 or 4 accordingly. This is the code I am using.

Private Sub ToggleButton1_Click()
With ToggleButton1
.Caption = "Goal 1"
End With
Dim rCell As Range
If ToggleButton1.Value = True Then
For Each rCell In Range("P2:P99")
rCell.EntireRow.Hidden = rCell > 1
Next rCell
3) Else
Range("P2:P99").EntireRow.Hidden = False
End If
End Sub

I have three questions -

1) This code works to show Goal 1 and by changing the >1 value to <4 I can make it work for Goal 4 - but I can't work out how to show the other Goals, 2 and 3.

2) Is this code an efficient way of doing what I want?

3) How can I make the "up/down" state of the toggle button actually relate to whether or not I am showing a particular goal? That is, if I click Goal 1 and then click Goal 4, I am showing Goal 4 but both buttons stay in the "down" state. I want the Goal 1 button to automatically return to it's "up" state when I click on another button.
