Hello,
I am wondering how to include 2 sliders in my experiment but I don't know if they should be included in a block or a survey. I have included them as a block because I saw an example where this was done, but for some reason I get an error when I do this. Below is my syntax:

<slider time_response>
/ caption="How much time has gone by (in s)?"
/ labels=("0s", "15 s", "30 s", "60 s (1 min)")
/ txcolor = (0, 0, 0)
/ range = (0, 60)
/ increment = 1
/showticks = true
/slidersize = (70%, 20%)
/position = (10%, 50%)
/defaultresponse = 0
</slider>

<slider mind_wander>
/ caption="How much of the time were you having irrelevant thoughts?"
/ labels=("0%", "50%", "100%")
/ txcolor = (0, 0, 0)
/ range = (0, 100)
/ increment = 1
/showticks = true
/slidersize = (70%, 20%)
/position = (10%, 50%)
/defaultresponse = 0
</slider>

<block questions>
/trials = [1-2=noreplace(time_response, 2=mind_wander)]
</block>


Any help would be much appreciated. Thank you!

A <slider> by itself is not a <trial>. You need to put your <slider> elements on one or several <surveypage> elements via the page's /questions attribute. A <surveypage> is a special kind of <trial>, i.e., you can either run it via a <block> or via a <survey> element (which is itself a special type of <block>).

<slider myslider>
...
</slider>

<surveypage mypage>
/ questions = [1=myslider]
...
</surveypage>

<block myblock>
/ trials = [1=mypage]
...
</block>
