I am creating a tool that calculates the percentage of a parcel that each soil type within the parcel takes up. My tool starts by selecting a parcel by parcel number then clips, dissolves by soil type, and should be adding a field for me to calculate the percentages in. The tool runs fine through the dissolve, but after the add field tool runs I receive no output feature. Also, I've noticed that when I run the field calculator after the dissolve I'm not able to select the shape area field in my calculation. Is there some error I am committing?
