Question Why is it always false?

Hi,
I'm new to UNIX and am trying to learn shell scripting in order to work on an interface that I inherited when a co-worker left. I need to be able to check to see whether a file exists to determine whether the FTP has taken place, but in testing, the if statement always evaluates as false, whether the file is there or not. Could someone tell me what I'm doing wrong?

Thanks.

if [ -e "$filechk" ]
do some stuff
else
do something else
