Regarding error id and error message

Hi,

in my code i’ve declared errorid ( i had given some integer like 608)
and a message assoicated with it. and again i had given errorid as 600
with the same message.

  when i was testing functionally i expected 608 but it displays 600

<608> expected but was
<600>
i think we can assign same message to different errorids…

 if not , say how to over come this problem...
