Positional parameters in if statement

I am trying to code an if statement that accepts two parameters and see if those parameters are in another file called teledir.txt. If it already exists in the file, it is to say "Entry Exists". If not, I add it to the file and say "Entry Added". This is the code I have so far:
Code:
if [ $# -eq 2 ]; then

                if grep  "$1:$2" teledir.txt; then
                        echo "Entry exists"

                else
                        echo "$1:$2" >> teledir.txt
                        echo "Entry Added"              
                fi

fi


When I run this, if I enter a name and number that is in the file, it says entry added and places it into the file. I'm new to the command line but what am I missing?
