<![CDATA[Rails Forum - Ruby on Rails Help and Discussion Forum - return undefined error]]> http://railsforum.com/viewtopic.php?id=46552 Sat, 22 Oct 2011 11:40:31 +0000 PunBB <![CDATA[return undefined error]]> http://railsforum.com/viewtopic.php?pid=145895#p145895 Hi - I have been testing some code for using the results with Google maps. The calculations are fine, but when the value is returned I get an undefined error. Any help would be appreciated.

Also, my editor is highlighting the following line with an error:
yres = (ycalc[yi] / ydiv);
