first and the most important thing is to have either two forms, one as a search page and 1 to display the data. O the combo on the same form as the data.
All on one page. When you click on the combo box and put it onto your table, it will come up with a wizard option, then select find record option,
If you have a seperate page as the search option, then you could try this. Just have two fileds on your form, student name and student address, make sure the data comes from your table, then add a buton, in the wizard that comes up, choose record navigation and find record, this will bring up the familiar find bar, just enter the name of the student and it will find the record. NOW add a button again in the wizard choose the open form and choose the form with the students full records and link the NAME on each form, (easy with the wizard) or is you set us a primary key on the table ie Student ID link these two together.
Now when you goto the search page just click on the search button, enter the nam, the record will come up, then click on the new button you added and your other form should come up with the student records.
IF not give us a shout, this is the easy way of doing this, you could add boxes to type in the student name and have all the records narrow down till it gets to the correct record, but this gets very messy.
