I'm attempting to create a custom function and the getrelatedrecords is not expanding to give all of the argument options normally associated with that function.  We need this to work reliably.  Also, I've noticed sometimes when I pull up an existing function to edit it, the text of the function never loads.

In addition, with respect to the getrelatedrecords function, is it possible to start with the Potential and pull the related Account, or does it only work for grabbing an Account and pulling the related Potentials?
