How do I add google map api code to dmx google maps?

Hello,

I am new to wappler and coding in general. I am trying to build a step by step app that has maps on different pages and on the final page it adds each of the markers per page all together and creates a polyline.

I have manage to make it work on the index page within the script tag. However, I then tried to make the pages and the map does not seem to load after clicking continue from the page before it. I also would rather link the dmx markers to the dmx google maps instead of what I have at the moment with static markers [coordinates].

So is there any way to add code to the dmx google map and the markers so they can be all linked together and I can add/update on drag the polyline?

I’ll greatly appreciate your suggestions,

Thanks.
