Javascript for pdf form

[Guest jennifer]

I have never written javascript code before. I have imported a file into Acrobat Professional 8 and made it into a form. Most of my fields are finished and calculate properly, however there is one area that I have to write a custom javascript. Essentially what I want to have happen is when a customer types in a group size, which can be any number between 10 and 50+, the rest of the fields need to automatically calculate to achieve a total price per person for that group #. (I don't want them to be able to enter in their own discount) For example:Base Rate is $30.00 per person (Field #1) group size: 25(Field #2) discount based on group size: $1.00 Off up to $8.00 Off(Field #3) new rate: base rate minus discount(Field #4) Total group rate per personFields 1 & 2 are what I am having trouble with. Do I use an If Statement or If…else Statement or what?If anyone can help me I would appreciate it so much!

You might start by posting what code you already have. Also, try describing how the discount is calculated in plain english - that'll make turning it into javascript easier.
