Hi, I want to give a number for each question when randomizing block. | XM Community

Hi everyone, I am super new to JS.

Basically, I am randomizing my blocks but I would want subjects to know which question they.

First, I put an Embedded Data "counter"=0 in the survey flow.
Then, at the beginning of each block, I have a page displaying "This is question ${e://Field/counter} "
Lastly, I have JS for each block like this:

Qualtrics.SurveyEngine.addOnload(function()
{
counter=counter+1';
});

But then it does not work at all. The counter is not changing.

I would appreciate it if anyone could help with this. Thanks a lot.
counter is a JS variable, not an embedded data field. You can update the counter in the survey flow like this:
```
counter = $e{ e://Field/counter + 1 }
```
Under your randomizer add a group for each block, then each group will contain the counter increment and a block.
@TomG Thanks a lot, I tried the code, it turned with following error

"Invalid JavaScript! You cannot save until you fix all errors: Unexpected token { "

It seems like qualtrics is not reading the counter properly?

That line goes in an embedded data block in your survey flow, not in JavaScript.
