Help with scope issue

[JessicaKnight1]

I am using this code as an example for my own coding: https://developers.arcgis.com/en/javascript/jssamples/query_buffer.html

I want to be able to have the user click a button to trigger the buffer/selection to be carried out rather than it just the map loading, but I can't figure out how to do that. Anyone have any direction for me? I'm a novice with coding, so I may be missing something easy.

Excellent. Thank you both for the guidance. Seems to be working now that I changed it to dojo.connect!
