It doesn't. Those are two entirely separate things.

If you need different messages tied to different sets of questions, set up separate <surveypage>s.

I see what you mean. How does a surveypage's stimulusframes correspond to its questions, though?

To display elements on a <surveypage>, you use the page's /stimulusframes. Ideally, though, you should avoid that and use <caption> elements displayed via the page's /questions attribute instead.

You cannot /branch from a <trial> to a <survey>. A <survey> is a special type of <block>, and branches generally need to be at the same "level": I.e., you can /branch from a <trial> to another <trial> (a <surveypage> is a type of <trial>), but not to a <block>. Conversely, a <block> can /branch to another <block>, but not to a <trial>.

Okay, I now understand that <survey> is a type of <block> and <surveypage> a type of <trial>. However, if I have two questions that I want answered on separate pages, but I need them to follow the display of each image, how do I do this? 

Maybe I could have a <survey> with each question as a page. Can you branch from a trial to a survey?

Dave, thank you so much for your response. You've been a tremendous help!

Quick question: if I want there to be text elements in my surveypages that are defined elsewhere, how would I do this? Stimulusframes? Even if there are 2 questions?

Just sum the the ratings and latencies up by category and divide by N.

<values>
/ currentcategory = ""

/ cat_a_q1_sum = 0
/ cat_a_q2_sum = 0
/ cat_a_rt_sum = 0
/ cat_a_n = 0

/ cat_b_q1_sum = 0
/ cat_b_q2_sum = 0
/ cat_b_rt_sum = 0
/ cat_b_n = 0

</values>

<expressions>
/ cat_a_q1_meanrating = (values.cat_a_q1_sum/values.cat_a_n)
/ cat_a_q2_meanrating = (values.cat_a_q2_sum/values.cat_a_n)
/ cat_a_meanrt = (values.cat_a_rt_sum/values.cat_a_n)

/ cat_b_q1_meanrating = (values.cat_b_q1_sum/values.cat_b_n)
/ cat_b_q2_meanrating = (values.cat_b_q2_sum/values.cat_b_n)
/ cat_b_meanrt = (values.cat_b_rt_sum/values.cat_b_n)
</expressions>

<block myblock>
/ trials = [1-8 = noreplace(cat_a_trial, cat_b_trial)]
</block>

<trial cat_a_trial>
/ ontrialbegin = [values.currentcategory = "a"]
/ stimulusframes = [1=a_stim]
/ validresponse = (0)
/ trialduration = 3000
/ branch = [surveypage.rating]
</trial>

<trial cat_b_trial>
/ ontrialbegin = [values.currentcategory = "b"]
/ stimulusframes = [1=b_stim]
/ validresponse = (0)
/ trialduration = 3000
/ branch = [surveypage.rating]
</trial>

<text a_stim>
/ items = ("A1", "A2", "A3", "A4")

    values.cat_a_q1_sum += slider.q1.response;
    values.cat_a_q2_sum += slider.q2.response;
    values.cat_a_rt_sum += surveypage.rating.latency; };

/ range = (0, 100)
</slider>

/ caption = "Q2"
/ range = (0, 100)
</slider>

<data>

Just to outline my objectives: 
- I would like there to be an average slider response for both questions divided by category (this is what I was trying to get at by assigning category values)
- It would also be great if those could come with an average latency, which seems to be a bit more straightforward in Inquisit
- I think that since I used a lot of branching/responsetrial type of stuff, I'm concerned I won't be able to understand what a certain value/response is referring to....agh.

I've combed the boards and the tutorials, but please let me know if there is a similar template I can work with. This has been very helpful in the past.
