If(Contains(${Potentials.Elec Incentive Paid to?}),'Guardian',${Potentials.Approved Elec Incentive Amount},0))

So essentially, if the field labeled Potentials Elec Incentive Paid to? has the word Guardian in it, I want to pull the amount from the field labeled  Potentials.Approved Elec Incentive Amount. If it does not have the word Guardian in it, then it should place a zero instead.
