Hi,
Conversion not seems to be a problem as belwo hardcoded line ran correct for me
                Session["paid"] = 0;
                int paid1;
                paid1 = (int)Session["paid"];

So please put break point in below line.
paid1 = (int)Session["paid"];
And before executing this line, see what's the value for "Session["paid"]". I am almost sure it may contain some invalid entry during run time. Just debug and confirm the value in side "Session["paid"]" before executing the above line.

not Int, write Int32 and in ToString() 's' is capital...

int paid=Convert.ToInt32(Session["paid"].ToString());

Hi,
Please check below line that what value stored in Session
session["paid"] = radiobutton1.selecteditem.value
It should be numeric. More over tell that what's your error message.

if the radiobutton is inside gridview then you cannot access it directly this way..

you have to use as

RadioButton rb=(RadioButton)Gridview1.FindControl("")

session["paid"] =rb.SelectedItem.ToString();
