You have to add the attribute 'SELECTED' to the option tag that you want 
to be selected. To do this, you should recover the old value from the 
database and pass it to printbox(). Then change printbox() to create the 
tag using a loop over the value. For each value, check to see if it is 
the same as the value passed in and generate the appropriate option tag.
