[Roy]

try to do this crosstab insert form, where on colums clickevent i open a
small form to insert values in a column of the crosstab form.
the problem is after exit the form, i want to refresh my crosstab form, i do
a requery and i dont get any error message, but the crosstab form in realaty
doesn't change.
do you know the event and on each form should i be requery??
crosstab form is a subform.
