Tamar,
maybe my basecombo is a copy of yours, otherwise it is a copy of the basecombo in 1001 Things.
Me too, never ever have had any troubles with it.
Now today, sorry yesterday, I faced this, for me totaly incomprehensible situation:
on calling requery()
which has following code in it:

Local llItemExists as Integer, ;
	lcAlias as String, ;
	lcFieldName as String, ;
	lcTable as String, ;
	lcTableName as String, ;
	lcValue as String, ;
	liLstID as Integer, ;
	liLstcnt as Integer, ;
	loSource as Object
	

lcTable = This.ControlSource
lcAlias = Alias()
Store Juststem(This.ControlSource) To m.lcTableName
Store Justext(This.ControlSource) To m.lcFieldName
Select (m.lcTableName)
loSource = This.ControlSource
lcValue = Evaluate(loSource)
*******************************
lItemExists = .F. && assume the value isn't in the list.
liLstID = 0
For liLstcnt = 1 To This.ListCount
	If This.List(liLstcnt) = m.lcValue
		llItemExists = .T.
		liLstID = liLstcnt
		Exit
	Endif
Endfor
If llItemExists
	This.Value = m.lcValue
Else
	If Empty(Alltrim(m.lcValue))
		This.Value = .Null.
	Endif
Endif

*******************************

lcValue = evaluate(This.ControlSource)

Select (m.lcAlias)

on line: For liLstcnt = 1 To This.ListCount it errors
and when I than look/examen This.List in my debugger I see the situation as in the first screenprint. Moreover pemstatus(This,'ListCount',5) returns .T.
The requery of the combobox is called in both the Form.init and in the Page3.activate. Have now first removed call from .activate and also from the Form.init, and all goes well, except, ofcourse my combobox is not showing the value of the ControlSource on starting - pitty, but suppose my user will have to live with that, unless of course you DHL me your laptop :)
However, joke's aside, do you have an idea what else I could use to determine This.ListCount is not given that error?
Thanks for replying
