The title says it all.
The home page will include a simple input box where people will enter a number, up to three digits.
The user will submit the number, and we'll show a response text accordingly. (Like "too little" for 1-5, "moderate" for 6-10, "high" for 11-30, "too high" for 31+
We'll save each entry to a database, and calculate the average number (total number, divided by number of entries) and also show this to the user.
We'll also say "you're above/below the average"
That's pretty much it! I need this coded and implemented ASAP, hopefully today!
