Hi,
I am getting this value error in my report. i am using pagination fro
my report. I have only 2 records in my database. so in order to check
whether my pagination works i gave
{ % autopaginate Data 1 % } so that each record will get displayed in
two different pages. when i generate my report the record in the 1st
page is getting generated but when i click on the 2nd page link it
displays me this error. can any one help me what might be the reason
and solution for this.
