I'm sorry to say that the questions and survey format of your step goals survey are not designed in a way that they can be filled in by an actual person.
I went to the step goals survey because I love to help and find the subject interesting, wearing a tracker myself.
But I got stuck on the page with questions 15-18 and because I don't want to fill in fantasy answers or lie. There should be an option to fill in or select "I Don't know"! Otherwise people will fill in made-up answers.
I.e. question 16 "What percentage of your steps do you believe come from walking versus other physical activities such as running?" - I don't know. But the test requires a number, and refuses to go on to the next page if you don't fill in a number. There should be an option to fill in text (as opposed to require numbers), or to select an option "I don't know". You're encouraging the users to make things up completely if they don't know now, which devalues the answers you get.
And question 15 "Approximately how far, in miles, do you think is 10,000 steps?" has the opposite problem: it demands too rough an answer. It didn't accept my answer because I had rounded the miles to decimals. Why would you force the user to fill in whole miles (an incredibly big measurement, when talking about walking) when they do know a more refined answer?
You really should take another look at the format of the survey, particularly the absurd requirements of the formats of the answers.
