AmCharts (free) plugin throwing error

When I try using amcharts free plugin I get this error:

Element amChartsSerial A

The plugin amCharts / element amCharts Serial threw the following error: ReferenceError: AmCharts is not defined
at pushData (PLUGIN_amCharts-initialize–amCharts-Serial-.js:40:31)
at (PLUGIN_amCharts-initialize–amCharts-Serial-.js:36:4) (please report this to the plugin author)

I am following this tutorial that is on their website:

Anyone knows what I am doing wrong?

Turns Out I figured what was wrong:

There is a bunch of things you have to fill in the chart style section order for it to work… It will be marked in red for you to fill, but bubble doesn’t thrown an “issue to fix” warning on the editor
