I have 3 combos in a form (cbo1, cbo2, cbo3)the second combo cbo2 value depends ond the value chossen in cbo1 and the same happends with cbo3.

When I move the pointer in the table, I allways rebuild the cursors on which cbo2 and cbo3 are based calling a function.

The function is below:

* Get value of combo1 to update cbo2
SELECT("v_clientes_")
cbo1 = v_clientes_.loteamento
SELECT nome_num, codigo FROM quadras WHERE DELETED() <> .T. ;
AND cod_loteamento = cbo1 ORDER BY nome_num INTO CURSOR cur_quadras

* Get value of combo2 to update cbo3
SELECT("v_clientes_")
cbo2 = v_clientes_.quadra
old_area = SELECT()

SELECT numero, codigo FROM lotes WHERE DELETED() <> .T. ;
AND cod_quadra = cbo2 ORDER BY numero INTO CURSOR cur_lotes

WITH THISFORM
.cboQuadra.ROWSOURCE = "SELECT nome_num, codigo FROM quadras ;
WHERE DELETED() <> .T. AND cod_loteamento = cbo1 ;
order by nome_num INTO CURSOR cur_quadras"
.cboQuadra.ROWSOURCETYPE = 3
.cboLote.ROWSOURCE = "SELECT numero, codigo FROM lotes ;
WHERE lotes.Status = stat_venda AND DELETED() <> .T. ;
AND cod_quadra = cbo2 order by numero INTO CURSOR cur_lotes"
.cboLote.ROWSOURCETYPE = 3
ENDWITH
SELECT("v_clientes_")

*Problem is here -> when execute the next command it returns Error 1152 and *the combo disapears from the form. It seems that the Rowsource from cbo2 and *cbo3 = ""
THISFORM.REFRESH


* Cannot access the selected table (Error 1152)
* You have attempted to select a table outside the 32K work area range
* or are attempting to reference a file variable in a table that is not open.

* Using VFP6.0 + SP5

Does someone knows why it's happening and how to solve this ??

Thanks in Advance
