Programing issues!

[GlenW]

Guys the ground penetrating radar system is broken somewhere in the code. My debugger is saying it's from the attached file. It looks like a linked list structure but it segmentation faults trying to add values! There have been more pressing problems I've been fixing all day and I just don't have time to do this one as well. Can you guys lend me a hand; they say WPI kids are good with this stuff ? Just post the fixed c code and I'll give it a try.
