GAMLj Jamovi: Cannot drag cluster variable to Random Coefficients

[HildeH]

I am running into issues with Jamovi and cannot seem to solve it.
This is what is happening: IIn linear mixed models using the GAMLj module, after filling in the dependent variable and the cluster variable, I want to add the random intercept component for "Klas" (Class) under Random Effects. However, I cannot drag it into the Random Coefficients box.
I have already tried the following troubleshooting steps:
- Reinstalled the module.
- Restarted Jamovi multiple times.
- Tried a newer version of Jamovi (but could not install the GAMLj module there).
- Searched on this forums, which suggested it might be related to the measurement level of the variable. I changed this, but the problem persists.
- Tried launching Jamovi via the debug version.
All attempts yield the exact same result. Because of this, I am unable to continue with my course. I hope someone can help me out.

Hi,

This does sound like an issue which was addressed quite some time ago; let's start out by making sure you're using a recent version of jamovi, either 2.7 or 28 ... and let's begin by understanding why you were unable to install GAMLj; can you describe what happens?

Kind regards
