Code:
fileCount=`ls | wc -l`

or on bash
Code:
fileCount=$(ls | wc -l)

try this,

Code:
fileCount=`ls | wc -l`
echo $fileCount

although i seem to remember having to pipe to sed as well to remove all the blank spaces that wc returns

You don't need any external commands, let alone two of them:

Code:
set -- *
echo $#
