How can I access select control(drop down) ?

I would like to access the user value related to an option in Record_Updating event. The column is $rsnew[‘level’] but its values are numbers (0,1,2) having the following user values(displayed in the select control for user to select): 0=Parent, 1=Children, 2=Father.So what I want is to get this user values Parent or Children or Father just by having $rsnew[‘level’]

User Values can be retrieved as an array by: $this->Field->options()

And what it I want also to get the option of the rsold of the same field ?
