hi,

u are clearing the screen field in the PAI module of the program, but this cleared field value is passed to the screen only after the PBO. As error message is executed immediately after the CLEAR statement program execution stops there itself without executing the PBO module. So old value is displayed on the screen.

try this..

If screen-field LT 0.
  clear screen-field.
  message ..............
endif.
