help with extremely basic problem

Alright i'm having problems with this loop. Basically once the script is ran a parameter is required. Once entering the parameter it displays that in LIMIT. Alright so now the problem, I need my loop to ask my user for a number, and if that number is less than the limit then sum the input values until it reaches the limit.

example output of what i need

LIMIT = 50
please enter a number: 10
I = 10 SUM = 10
please enter a number: 15
I = 15 SUM = 25
please enter a number: 20
I = 20 SUM = 40
please enter a number: 15
done!

this is the code i have so far, the SUM PART is messed up and i dont know how to exit the loop and display done once it reached the limit.

Code:
#!/bin/sh

if [ $# -ne 1 ]; then
    echo "usage: help.sh LIMIT"
exit
fi

LIMIT=$1

echo "LIMIT =" $LIMIT

read -p"Please enter a number: " I

echo "I =" $I "SUM =" $I

while [ $I -le $LIMIT ]
do

read -p"Please enter a number: " X

echo "I =" $X "SUM =" `expr $I + $X`

done
