The problem is as followed:
I have 3 text boxes: Fee, Donation, Total.
Fee cannot be modified, and the user cannot type in this textbox
Donation starts at 0 and the user can change the value based on what they want to donate
Total needs to be updated based on what the user types in donation. It needs to be Donation+Fee
How can I use AJAX to make the Total textbox get updated on the fly based on what is entered in Donation?
