# display different question text based on previous answers

I would like to know 2 things:
* how i can display different words in a question based on the response of a previous question?
* how can i add calculations in a question based on responses of a previous question?

So for example, i have 4 questions:

1) Do you pay a price per hour or for the service as a whole?
a) price per hour
b) service as a whole

Then in the second and third question, i ask how much they pay per hour or for the service as a whole.

if 1=a
2) how much do you pay per hour?
a) 0-5 euro
b) 5-10 euro
c) 10-15 euro
d) etc.

if 1=b
2) how much do you pay for the service?
a) 0-10 euro
b) 10-20 euro
c) 20-30 euro
d) etc.

In the fourth question, i would like to display different words based on the previous responses in Q1-3:

2) are you willing to pay a higher [add word --> if Q1= a: price per hour / if Q1=b: amount] of [add result of calculation --> if Q1=a: upper limit bracket Q2 + 10% / if Q1=b: upper limit bracket Q2 + 10%] ?
