I've followed the instructions here: https://community.qualtrics.com/XMcommunity/discussion/comment/32547#Comment_32547 to integrate katex into a survey for displaying equations. Interestingly, when I use "preview question" on a question with embedded katex, it displays fine in the pop-up window, as below:
But when I use "preview block," "preview survey" or even just look at the published survey, I get a mess:
Interestingly, you'll see that the variable d_{blue, red flag} is actually displayed properly within that block.
I feel like maybe there's a command I'm missing somewhere that doesn't get triggered when doing the broader previews? Has anyone gotten math display to work properly (using katex or otherwise)?

equations displaying in question preview but not survey

+27Post your question html (as a code block).
+1Text block:
Globally/Always:
\\text{``Always between } t=1_1 \\text{ and } t=t_2:S\\text{"} means that the statement S must always be true for all time between t_1 \\text{ and } t_2. This is equivalent to \\text{``}G_{[t_1,t_2]}:S\\text{"}, where G stands for "globally"
Finally/Eventually:
Other Operators:
“∧” means “AND”
“∨” means “OR”
“¬” means “NOT”
“≤“ means “less than or equal to”
"≥“ means “greater than or equal to”`
Question JavaScript:
Qualtrics.SurveyEngine.addOnload(function() {jQuery(".katex").each(function() {
katex.render(this.innerHTML, this, { throwOnError: false });
});
});
Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
});
Qualtrics.SurveyEngine.addOnUnload(function()
{
/*Place your JavaScript here to run when the page is unloaded*/
});

+1I just realized that text block isn't the exact same text block example I gave previously, but all cases that have katex run into the same issue.
+1Hi TomG - thanks for the suggestion. It seems that removing defer and onload has helped some instances display correctly, but when I copy/paste your suggested edits to the text (removing the \\text{} tags), a few things happen:
The question-only preview gives this, with the text in the math font:
(As expected from the code, and not something I want.)
And the block preview very briefly shows up as the same thing, before quickly turning into this:
With much more red text going on, until it reaches "stands for "globally"". Any idea why that might be happening?
+1Dear all
I have the same issue as hoseasiu, my equations are displaying in question preview but not in survey. I tried the suggestions above but it didnt work
hoseasiu were you somehow able to solve the problem or has anyone an idea what I can do? Why is it a difference whether you look at the question preview or the preview of the survey?
Thank you!
my textblock is the other parts are the same as the parts from hoseasiu :
Median nicht direkt aus der Reihe der Merkmalswerte an der (mittleren) Stelle \\frac{n+1}{2} abgelesen werden. Stattdessen gilt: Md = 5.5 (Stelle q = \\frac{n}{2} = 4; Stelle q + 1 = \\frac{n}{2} + 1 = 5; Mittelwert der Merkmalswerte \\frac{x_{4} + x_{5}}{2} = \\frac{5 + 6}{2} = 5.5)
