The most obvious error is that you might be using apostrophes ' there
instead of backticks `.  Try using backticks and see if that fixes the
problems.  

(In bash apostrophes are just quoting characters.  Backticks say, evaluate
this first and then I'll work with the result.)

If that's not it, we'll have to come up with another thory.

all the best,
