>¿Character value? I'll test it, but the combo is initialized to numeric value in design mode and i want to return a numeric value. Now, even the combo doesn't shows the initialized value, if the user selects an option it returns a numeric value. If i set the init value to character one, what will be the return value when the user selects an option ?. I know that i can use val() to convert string in numeric value, but it seems not pretty.

As long as you use AllListItem to populate the list, you have no choice except character values. To provide numeric values, you should change list.rowsource to alias/fields with Int value in second field.
