hai... meaning of that error is.. your r missing or lose to pass the correct value into the variable...
for example...

->you are defining any variable..
->you are going to pass the value to the variable at dynamically
->your are using that variable in some place,like multiplication..
->if in case the value you are passing that variable is missing.. then it shows the error at multiplication process..Like "Object reference is not set to instance of object"

to check this or to solve this error

-> keep break points check every variable values at run time

->anything shows null value then try to solve that

good luck
