Decision trees in the exam

I drew a decisin tree in the exam but i had two outcomes coming out of an outcome?
We had 2 scenarios if we would have gone for the extension to the gym/whatever it was
1) increase or decrease in number of members
2) increase or decrease in price charged to members.

So you can see for an outcome of going ahead with extension, we had two more outcomes but there is no decision made in the middle (after going ahead with extension and before the two outcomes)
Is it valid?
I hope i am making sense here. How did you guys drew your decision trees?
