Update Subform by search

[eclypz]

I have a table, that contains data for students

Number;
Name;
School;
Street;
Code;

I want to have a form that contains, a txtNumber (text box to the user
put the number of student that want to search), cboSchool (Combo, that
allow the user to indicate what are the school to search for), and a
cmdSearch, that on click will search the record on the table, that
contains the student (number and School).

i want in this form to have the others txtboxes with street and code,
that the user will fill after find the record.

Example: i want to update the student number 35 from angelic school, i
choose in the cbo: Angelic School, and in the txtNumber fill with 35,
click on cmdSearch, it will appear

Number: 35
Name: John Doe
School: Angelic School
Street: (to be filled)
Code: (to be filled)

I though do it by using a form with a subform, but i'm having problems
with it... can any one help me?

Thanx,

JEC
