I am using the latest version 1.0.2-2 (e86c870879, 2021-01-15). 

the selection of a tray and insert divider tray and then setting the variables then looking for a live preview does nothing... ie: no box is generated.

I am and newbee user so i must be doing something wrong.

Documentation for boxes.py is here: https://florianfesti.github.io/boxes/html/index.html

I found nothing in the references that illuminate a caue of my problem. 

When I go into the Windows native section and run the following in Python command line 

Run the command pip install Markdown lxml affine (Note: If the command pip is not found, you probably forgot to add the Python installation to the PATH environment variable in step 2 (i did this when I installed the latest version of PYTHON)

that command line throws and exception.at install

any thoughts?

I am trying to use boxes.py to generate a type tray and I continue to get an error message "failed to execute script boxes" Any idea what the cause could be? 

1. Describe your OS (your computer's Operating System: Mac/Windows/Linux/etc. & version).
2. Describe if Inkscape was newly installed, or upgraded from an earlier version.
3. Describe the version of Inkscape and the installer you used (the file you downloaded from the web: .msi/.exe/.zip/appimage/other, PPA/Snap/Flatpak, dmg/other ). 
4. Describe any special hardware being used, like tablet/stylus, external drives or multiple monitors.
5. Describe any helper/assistive programs or keyboard modifiers (macros, languages, etc.).

Bonus points, if you:

• Attach* a screenshot of the issue.

I am using Windows 11 and recently upgraded Inkscape to version 1.4 the 64 bit MSI. The computer has 3 monitors and multiple internal drives but nothing else special with the computer.

The error message is just a pop up box with the message  "failed to execute script boxes"

Hello Tyler. 
I am going to shift gears for now and try to solve the problem on my Win 10 machine, The  extension I am wanting to function correctly is in the Boxes.Py type tray. 

On this machine I have installed Inkscape 1.3.2 because it is my understanding that this extension has been updated for 1.3.2. I used the .exe fie to install on this machine.

Below is the error text it displayed

I'm not sure if I have not asked the question correctly or given you enough information to help me solve my problem with this. Whatever it is I would truly appreciate a response from you.

All I am getting is NOTHING. Please let me know what I need to do.

Thank you.

If nobody responds here, it's because nobody has a solution for you.

The windows install instructions seem complicated. Check that you followed all the steps in this guide.

If that doesn't help, you should reach out to the boxes.py developers and users. I am neither.
