hi all. i have a little problem. im basically reading input from the user from the keyboard into the variable "phonenumber". I want to do a little error check to check if the user doesnt enter anything in for the value phonenumber.

i had this:

read phonenumber

if [ $phonenumber=" " ]
then
.....
else
.....
fi

but thatjust performs then instructions in between "then" and "else", but not "else" and "fi". any ideas?

thanks all in advance for your help.
