Hello! this may be so simple, but I'm having a hard time with it.
I want a few things to happen -
if the Approx trips per year is blank:
provide the sum of just the Registration price field & the Approximate travel field
If the Approv trips per year is NOT blank:
multiply the approx trips per year by the apprx travel cost, then provide the sum of that travel cost and the Registration price
it feels like an if statement, but I always have a hard time with the NOT blank if statements.
