I am performing a spatial join in which I sum the values for one polygon layer and assign that data to another polygon layer it intersects. For summed values of 7 or more digits, the calculated value is missing the first digit. For example, the join summation shows an answer such as 756,324, when the actual correct answer is 7,563,241. Any answer with 6 digits or less is correct.
Any thoughts as to the cause, or a solution?
