Shell Program Error undefined Variable?

Following is the script

echo "Enter the Sybase database where your want"
echo "to create the tables followed by a carriage return"
read database

echo "Enter the center followed by a carriage return."
read center

read username

echo "Enter your sybase password followed by a carriage return."

#create tables

echo "creating airspace table"

echo "done creating airspace table"

#create fpa table

echo "creating fpa table"

echo "done creating fpa table"

#create node_latlng table

echo "creating node_latlng table"

      isql -D $database -U $username -P $password < /home/tmclaugh/test/node_latlng.sql.tmp

echo "done creating node_latlong table"

echo "all three tables should be in the database you selected in Sybase"

The error I keep getting says that center is an undefined variable?

Also remove the "!" character from the output redirects.

For example,

sed -f "s/CENTER/$center/g" /home/tmclaugh/test/fpa.sql >! /home/tmclaugh/test/fpa.sql.tmp

should be

sed -f "s/CENTER/$center/g" /home/tmclaugh/test/fpa.sql > /home/tmclaugh/test/fpa.sql.tmp

"read variable" is not  C shell syntax.

it looks like a Bourne/Korn script, not a C shell  script.
