selection screen

hi frnds,

my requirement, i have a selection screen with a select-option. After the user inputs the value in the select-options, i have to display a screen which shows some of the values which may not be correct. then the user will

go back to the selection screen to re-input the values..

any suggestions to do this elegently. Now im using some crude method. plz remember that, the displayed values will be more than 1, so i cant use a 'message'...

all answers assured points..

regards,

Madan...
