If comparisons in ksh

I am converting a program from csh to ksh and having a lot of problems with the if statements.

here is the the basic program with the problem
#!/bin/ksh
#
#
set nohup
set noclobber notify
#

tput clear
echo " "
echo -n "Enter Your CHOICE :"
read CHOICE
if (-n"$CHOICE")
then
echo "Choice is $CHOICE"
fi

when I run it a enter one as the choice I get the error

Enter Your CHOICE : one
./vc_menu4[12]: -none: not found

I have tried several variations to basically check if $CHOICE is null and then run the "then" clause. Can anyone help here. Thanks.
