thanks for the information link, but the problem is that when I enter the amount into the Column C input for US Source ECI it flows to the wrong column on the form.  It flows to Column E which is US Source FDAP.  I have not been able to find a place where I can get anything to flow on the K-2 to the US Source ECI column. 

This appears to be a coding error that needs correcting so that the input flows to the correct column. All of the other columns appear to flow correctly.
