JS Print Button - Problem with Async as it calls External Script.

Our website uses a JS script on the main page. This specific JS script is called a different way as it provides info for the print service. The main calls this script like this. <script async type="text/javascript"> (function() { var p=[login to view URL]("script");p.type="text/javascript";p.async=true; var h=("https:"==[login to view URL]"https://":"http://"); p.src=h+"[login to view URL]"; var s=[login to view URL]("script")[0];[login to view URL](p,s); }).call(this); [login to view URL] = 'async'; </script> Which in theory should load async, but does not. The headers of that page loads another external script like this var timestamp = "03-03-2019 18:24"; var checkoutUrl = ('https:' == [login to view URL] ? 'https://' : 'http://') + '[login to view URL]'; var baseAssetUrl = ('https:' == [login to view URL] ? 'https://' : 'http://') + '[login to view URL]'; if (![login to view URL]) { var head = [login to view URL]('head')[0]; var script = [login to view URL]('script'); [login to view URL] = 'text/javascript'; [login to view URL] = baseAssetUrl + '/storage/javascript/[login to view URL]'; [login to view URL](script); } I have copied these two external scripts locally to /waitme/[login to view URL] /waitme/[login to view URL] Can these also be merged into one script instead of one calling the other? --- IDEAL SOLUTION Merge the 2 external scripts into 1 local script and only have the main page button call that script .... When the button is clicked, Not Everytime the page loads. --- a fantastic review will be given if you can get it to load async, Or not at all if it is called when the button is clicked... even better.
