Create Point Graphic from Input boxes values

victhomas — Fri, 10 Dec 2021 23:37:34 GMT

Hello all,

I'm having trouble creating point graphic on a map from input values box. Below are the code that I have. I'm trying to get the lat and long values that is entered to plot on the map after the button is clicked. Any help on how to get the global input values into the require() to generate the point graphic would be appreciated. Thanks,

Vic,

Here is your code working:
