Proper syntax for Sub?

I am working on a project that incorporates an activex control. I have a series of checkboxes that interact with that control.

Currently, I have a function for each checkbox, which seems a little silly. I am trying to reformat the Sub to accept two parameters, but am not having any luck.

Calling statement:
<INPUT type="checkbox" onclick="GenToggle('Office Locations', window.document.Form1.Office)" id="Office">Office Locations

Sub:
Private Sub GenToggle(layername,chkname)
Dim myMap
Set myMap = getMap()
If chkname.checked = True then
myMap.getMapLayer(layername).setVisibility(1)
myMap.refresh()
Else
myMap.getMapLayer(layername)setVisibility(0)
myMap.refresh()
End If
End Sub

Any help is greatly appreciated...

As I can see - you forgot to write a dot in your Sub:

Private Sub GenToggle(layername,chkname)
Dim myMap
Set myMap = getMap()
If chkname.checked = True then
myMap.getMapLayer(layername).setVisibility(1)
myMap.refresh()
Else
myMap.getMapLayer(layername).setVisibility(0)
myMap.refresh()
End If
End Sub
May be it will help you?

Good Luck!
