To make it, I make a consultation SELEC. The problem is that I need that when the user changes the value in a registration, then be reflected automatically in the sum, without waiting to that this it is kept (since the SELEC doesn't take the change until he/she keeps the registration). Does some of you know as making this?

Running a select per value change is time consuming and also doesn't get buffered records as you said. Instead do only one SQL into array as parent changes. Add code to lostfocus of numeric fields that effect the sum. You only need ArrayValue + (Newvalue-Oldvalue). This approach is fast. ie:

* When of num field
scatter memvar
* Lostfocus of control
aSum[1] = aSum[1] + ;
  (eval("m."+;
     substr(this.controlsource,rat(".",this.controlsource)+1)) ;
  - this.value )
