Help Understanding While Loop

OK, I've been working on an sh script and I'm almost there. In the
script, I created a 'while read' loop that is doing what I want. Now I
want to keep track of how many times the loop executes. Thus I included
this line between the 'while read' and 'done' statements:
count = $(( count + 1 ))
I've tested this by adding an 'echo $count' statement in the loop and it
increments by one each time the loop runs. However when I attempt to
call $count in an 'echo' statement after the 'done', the variable is
null. Thus I assume that $count is only local to the loop and I have to
export it to make it available outside the loop? What must I do?
Thanks for your help,
Drew
