this is not enough info to tell you exactly what you are doing wrong, but - you are calling on a variable that you did not assign a value to. It could be something as simple as:

int a; // giving it no value

int b = a; // as you can see, you didnt *** value into a, so you are calling on a null value

Please provide the code so we can look into the problem!

Thanks for replies.

actually i m totally new to asp.net. i have to modify an already existing project. so its more confusing bcoz i dont know very much about the actual code. the strange thing i notice that website run properly for some time at starting. and after some time it will show nothing except the system.nullreference exception on each page. does this information help to u understand the problem??

is it related to something like cache expired? i dont know abt this problem and that's why i m searching net for a solution.

thanks
