    1. Please post on this forum sensibly. People will be help you no matter how many exclamation marks you use in the title.

    2. Potential cannot be calculated at a point. Only a 'potential difference' between two points can be calculated. Generally, the potential at infinity is taken to be zero and all other calculations are made respect to that. Hence, potential at a point means the 'potential difference between that point and infinity'. Under this definition, potential is zero only at infinity.

    but infinity is not in the field. it is abroad
