Is it possible to have a dropdown that shows or hides another field? And if so, how?

I'm trying to build a rather complex form that will calculate our diving trips expenses.
And depending on the boat being a 2-stroke or a 4-stroke i need to ask for how many liters of petrol was used.
I don't want it to be a multipage form, because then nobody will use it.

I've built this in Excel, but that of course requires the user to have excel on his computer, so that is not optimal.

I also need to be able to write how many participants were on the trip, and then it should show fields for entering their names depending on the amount, is that possible? And if so how do I do that?

I see, that is bleeding brilliant!
One thing I don't understand though, I have a dropdown, but it shows all the items with checkmarks? I thought it should show a dropdown, so one could only select one of them?

Hmm, I must've selected the wrong one, I just replaced it, and now it looks fine...
