My Google map shortcode is not working, how do ...

You need to get the iframe code from google maps and then copy the “src” attribute url and put it in your shortcode. For example if your iframe code is :

<iframe marginheight="0" scrolling="no" src="http://maps.google.com/maps?q=897+West+Broad+St.+Columbus,+OH.+43222&ie=UTF8&hq=&hnear=897+W+Broad+St,+Columbus,+Ohio+43222&gl=us&ll=39.958996,-83.024507&spn=0.009095,0.021136&t=m&z=14&vpsrc=0&output=embed" marginwidth="0" frameborder="0" height="350" width="425"></iframe><br /><small><a href="http://maps.google.com/maps?q=897+West+Broad+St.+Columbus,+OH.+43222&ie=UTF8&hq=&hnear=897+W+Broad+St,+Columbus,+Ohio+43222&gl=us&ll=39.958996,-83.024507&spn=0.009095,0.021136&t=m&z=14&vpsrc=0&source=embed" style="color:#0000FF;text-align:left">View Larger Map</a></small>

You should copy this part only :

http://maps.google.com/maps?q=897+West+Broad+St.+Columbus,+OH.+43222&ie=UTF8&hq=&hnear=897+W+Broad+St,+Columbus,+Ohio+43222&gl=us&ll=39.958996,-83.024507&spn=0.009095,0.021136&t=m&z=14&vpsrc=0&output=embed
