Get geolocation onclick issue (Using google maps api v3)

Im trying to build a map that shows the location when I click a button outside the google maps.

I am taking the map from the Google maps api v3 as the tell me to and I'm also able to get the user location with a maker and even the infowindow shows up but as soon as I add everything into a single function and try to call it from the HTML it doesn't work but the map keeps showing so I'm guessing the code doesn't have any errors. I'm probably missing something in my code.... .... .... I will leave my code here so maybe someone can help me out with this Thanks
