NO Conversion from mobile campaign

Hi guys,
after a few days of study i have tried to make a new campaing with a good CPA (€9,00) using ADEspresso and Facebook Ad.

The campaing is based on a landing page with a quiz questions and at the end a button for allow user to register on weekly service news.

I have generated an image (in attachment) this image should simulate two buttons for allow to user to access on landing page.

I have set a small daily budget in this way:
age: 13 to 17 5€/day
age: 24 to 34 5€/day

for 2 entire days.

So the post reach a lot of user (5k) in a few hours (12) but i generate only 158 clicks and 0 conversion.

I think i wrong something.

(Sorry for my english, I'm studying this too )

I'm preparing a new campaing, this time using:
1 image
3 different text
1 pre-landing page made by me

I hope on some helps bye
