Hi Group/ Pierre GIRAUD/Damien,
I am very much thankful for your valuabel suggestions.I got my problem solved with the help of your suggestion.The problem occured because of the extra lines after my code. I think it should not be a problem because nothing written in those lines after my code.Any way after removing those extra lines i got my error rectified.
Thanking you once again.
Regards,
venu.

I didn't take a look at your code but the error you sent us isn't really
explicit.
Probably, you have an "echo" or "print_r" somewhere that prevent the
error to display correctly.
Are you able to check this and send back the real error message on this
list ?
Regards
Pierre GIRAUD
