==================
I have tried for several hours to get this to work with no avail. I have consulted several threads previously, with considerable care to make my code identical with no errors (e.g.,  NOT double quotes in double quotes)

forums.limesurvey.org/forum/design-issue...ge-with-if-condition

forums.limesurvey.org/forum/can-i-do-thi...onal-show-for-images

forums.limesurvey.org/forum/can-i-do-thi...n-previous-responses

No matter what I do, it won't accept my IF logic, despite putting it into the source code. I keep getting an image popping up NO MATTER what I select. I have tried multiple iterations of referring to the question previous (e.g., changing the question name, using answers that are numeric only etc. etc.) Always it looks like this, with the IF statement showing up for some reason (see image attached):



My code is below:

{if(
(tt.NAOK=="t3"),

"<img src='/upload/surveys/998569/images/SampleLabelPlaceHolder2.png' />", "<img src='/upload/surveys/998569/images/units.jpg' />")
)
}

My survey is attached.

A more "complicated version" to be implemented is below as well:

{if(

(tt.NAOK=="t3"),

'<img src="/upload/surveys/998569/images/SampleLabelPlaceHolder.png" />',

if(
(tt.NAOK=="t2"),

'<img src="/upload/surveys/998569/images/SampleLabelPlaceHolder2.png" />', '<img src="/upload/surveys/998569/images/units.jpg" />')
)
}



 

Having imported your survey I see two things
 
1. There are nested quotes.
Obviously you used the Iline HTML editor. This type of editor has a strange way to handle quotes.
Better you use the source code editor.
Select the editor in your personal settings
 

2. Remove one closing bracket.
