same code, buttons failed to work after a few successes

Hello everyone, im new to animate and i am trying to make a simple html5 canveas-based interactive animation with mainly navigation buttons. 

I use the gotoandplay/stop code from the code snippets a lot to build the buttons, they worked pretty well for the first few buttons, but i just couldn't make them work when i try to build more of them. Considering the numbers of the repeating codes I use, and the simple change I made (just changed the frame number as the instruction says), I think it would not make many sense to the post the whole codes here. 

Google console gives me error report when i publish the animation, of which i think might be helpful to post them below:

Uncaught TypeError: Cannot read properties of undefined (reading 'addEventListener')

I have taken advice from the other answers from the community to make a few changes to the settings (for example disable the advance layer), but it sadly didn't fix the problem. 

I feel like it wouldn't be a really complicated problem as i only use the basic code from code snippets, but i just couldn't figure it out for days. could anyone help me with this... 😭 (i hope my description makes sense, but please let me know if there are details that i didn't make clear). Thank you in advance!
