From here I am a little lost on how to get the camera to take pictures every few seconds for a couple of hours. Do I need another Script in addition to what is currently on there or is it already there?
There is a simple intervalometer script that does exactly what you ask included in the most recent versions of CHDK. Look on the SD card under CHDK/SCRIPTS/4Pack/Lua/interval.lua or CHDK/SCRIPTS/4Pack/uBasic/interval.bas (same script - different scripting languages).
There are more complicated scripts posted on the wiki and forum. Search for "intervalometer" and find things like :
http://chdk.wikia.com/wiki/UBASIC/Scripts:_Ultra_Intervalometer. You need to copy these script to your SD card ( typically the /CHDK/SCRIPTS directory) and load them from the script menu. Don't forget to add a .lua or .bas extension to the filename as appropriate.
If you want to try something other than CHDK, there is a different program called SDM that also supports some of the CHDK type functions - google for it.
Also, please don't cross post the same message to more than one thread. The people who can answer your questions tend to monitor all new postings.
