Trouble using stroke weight script

[Connor24501606tet8]

I found a thread where @Ton Frederiks mentioned a script for changing the weights of strokes having different original weights: https://community.adobe.com/t5/illustrator-discussions/is-there-a-way-to-increase-the-thickness-of-a...

But I'm having trouble using the script. I pasted it into a .txt file, changed the extension to .jsx, and tried opening it in AI (File>Scripts>Other Script...), but I got an error message that said:

Error 1302: No such element

Line: 2

->  var aDoc = app.activeDocument;

I also tried it as a .js file. I've attached the original .txt file (I think). Any clues as to what's going wrong here?

Try this one, it works for me: https://shared-assets.adobe.com/link/5b536482-0a3a-4468-4baa-5c70b118e397

Ran into the same problem but was able to get it by dropping it into the scripts folder. Thanks for your help.

Good to hear you've got it working.
