Thanks Jim, i resolve the problem, in the Init i call a refresh of the form, and now works great.

>Well, Lius, it seems unlikely that this would work in either form... are you sure that the first form doesn't, sometime before the first use of the combo, replace the RowSource with a VARIABLE set from the property?

>The "excuse" for this behaviour is that in THIS case the actual SQL is executed 'outside' of the environment (of the form OOP) and so cannot interpret THIS.... Personally, while I understand the nature of the problem, I think this STINKS. To me it represents a design flaw that should have been fixed by now.

>>I have a form, in this form I have 2 combos, each one of them are RowSourceType=3, and Row Source goes like this:

>>Combo1= Select nombre_cad,codigo_Cad FROM cadenas INTO CURSOR sys(2015)
>>
>>Combo2= Select nombre_tie,codigo_tien FROM tiendas WHERE codigo_Cad=THISFORM.Combo1.Value) INTO CURSOR sys(2015)
>>
>>

>>In the Interactive Change of the first combo, I make a Requery to second one.
>>Both combos, are boundto=.T., and boundcolumn=2, and in this form they work great, but in a new form that I'm using, I'm getting this error:
>>
>>THISFORM can only be used within a method, and the help file says this:
>>
>>One of the following commands was used outside of a method: THIS, THISFORM, or THISFORMSET.
>>
>>You used the statement in a procedure, but it can only be used within a method.
>>Move the THIS, THISFORM, or THISFORMSET command into the appropriate method.

>>Ok why this works in the first form, and it doesn't works in the second one?.
>>Thanks for your time.
