I am adding a checkbox prompt called Island Base in all base cabinets.  If it is checked, the bottom is made to equal the cabinet width, the bottom x origin is moved left by the amount of the side thickness, the sides height are reduced by the bottom thickness, and the sides z origin is increased by the bottom thickness.  I would also like to append the product name with the word "Island".  What kind of formula do I need, and where do I need to put it?
