How to add this choropleth plugin

I did Auto Insert and Frontend Only. Still the error ??

Fatal error: Cannot redeclare leafext_enqueue_geosearch() (previously declared in /home/bariscop/public_html/wp-content/plugins/insert-headers-and-footers/includes/class-wpcode-snippet-execute.php(268) : eval()’d code:2) in?/home/bariscop/public_html/wp-content/plugins/insert-headers-and-footers/includes/class-wpcode-snippet-execute.php(268) : eval()’d code?on line?1

Either you accidentally pasted the code twice or you have 2 maps with geosearch on the page. Nevertheless – I changed my code.

In the example the code used in the map and the code displayed is the same, it is the same source where it is read.

Excellent, this works! Thanks much!
