Dynamically show image based on previous responses was created by FRGDan

Hi guys,

I'm wondering if something like this is possible (out of curiosity)

I have a Question with 5 options, and in a later question, I wish to show the corresponding image to the option that was selected.

E.g.:

Q1. Select one:
1
2
3 <- selected
4
5

Text Display: [Image 3 shown here]

Now.. The obvious solution to this? Just have 5x Text Display and use normal conditional routing. But I'm wondering, can I achieve the same result with expression manager?

I imagined something like this, however this will cause errors:

Code:

{if(Q1.NAOK == 1,
"<img src='https://via.placeholder.com/500x90.png?text=Image+1' />,
  if(Q1.NAOK == 2,
  "<img src='https://via.placeholder.com/500x90.png?text=Image+2' />,
    if(Q1.NAOK == 3,
    "<img src='https://via.placeholder.com/500x90.png?text=Image+3' />,
      if(Q1.NAOK == 4,
      "<img src='https://via.placeholder.com/500x90.png?text=Image+4' />,
        if(Q1.NAOK == 5,
        "<img src='https://via.placeholder.com/500x90.png?text=Image+5' />,
        ""
        )
      )
    )
  )
)}

More simple to undetsrand and update (in yours : you didn't close the " in first item (maybe elseware))

Code:

{if(Q1.NAOK == 1,"<img src='https://via.example.com/500x90.png?text=Image+1' />","")}
{if(Q1.NAOK == 2,"<img src='https://via.example.com/500x90.png?text=Image+2' />","")}
…

Hi Denis, apologies for the typo, I wrote that quickly as an example (the actual code needed to be written in a cascading style due to its complexity and need for prioritisation)

When I mean it wouldn't work like that - the same would occur in your example.

E.g.

Code:

<p>Only the image selected in Q1 should be shown here:</p>
 
{if(Q1.NAOK == 1,"<img src="https://via.placeholder.com/500x90.png?text=Image+1" />","")}
{if(Q1.NAOK == 2,"<img src="https://via.placeholder.com/500x90.png?text=Image+2" />","")}

Will break the expression and show something like this on screen:

(If I right click on the images and open as new tab, the URL contains html code pertaining to "Undefined Syntax" and "Undefined Variable")

It may be due to double-quotes inside double-quotes.

Code:

<p>Only the image selected in Q1 should be shown here:</p>
 
{if(Q1.NAOK == 1,"<img src='https://via.placeholder.com/500x90.png?text=Image+1' />","")}
{if(Q1.NAOK == 2,"<img src='https://via.placeholder.com/500x90.png?text=Image+2' />","")}

Cheers,
