I've come across a ridiculously infuriating problem.

I'm trying to load a simple bash script that cd's to a directory and executes a function, but whenever I sh the script, it ALWAYS tells me "can't cd /whatever/directory" (obviously this is not the actual directory)

For debugging purposes, I have set the directory name to things that DEFINITELY exist, such as /home/user/MyDocs/

I have run the command by itself in xterm with no problems, but it gets picky when I run it from a script.

I have chmod +x it and everything is as it should be. What the hell is wrong?
