Hi all,

Everything in my experiment works now, however in Pavlovia the text Hello World is on top of all my images. In PsychoPy everything works fine, but when Im trying to run it online, the text appears on my images. In my files and Builder I cannot find it, so I dont know how or where to delete it.

**OS** : Macbook M1 2020  
**PsychoPy version** 2024.2.4  
**URL of experiment:** [Xannah Voortman / IAT\_stereotypes · GitLab](https://gitlab.pavlovia.org/xannahv/iat_stereotypes)  
Project ID: 462637  
Original template: [demos / OpenIAT · GitLab](https://gitlab.pavlovia.org/demos/openiat). Project ID: 14096

Also, I tried running the experiment and one person completed it. When I download the results, I get 281 cvs files, that also contains data from the original template. Is that possible? And how can I only get results from my own experiment?

Hello World! normally appears when you try to display an undefined variable

> ReferenceError: varName is not defined This is one of the most common errors in online experiments It is also one of the easiest to solve. The issue is one of “scope”. To define a variable so it has scope across your whole experiment, all you have to do is assign it a value. Don’t edit your JavaScript to add “var” or “let” commands. To give your variable scope assign the value in a Begin Experiment code component tab outside any clauses (i.e. no Python indents). I usually s…

If you delete all the old data files and then sync they will be deleted online as well.

Hi, thanks for getting back to me. In my trial I have an image and text component, but previously it showed both at the same time instead of one after another. I fixed it with this code component in Begin Routine:

Is it possible that it has something to do with that? Im using images using excel. How can I add a scope to my variables? Do I need to edit some things in my excel file?
