finances calculating script
im looking for a script that would calculate a main figure and add a second figure to the first one but put this in a subtotal area so that area changes but the other 2 figures dont change. and i want the subtotal figure to be able to change daily so that every day it would add the second figure to the subtotal and each day repeats.
All this is an interest calculator on a page on my computer that is open and everyday it updates itself when the date changes and updates the subtotal figure so i can see what the amount currently is.
if anyone can help me i would be much appreciative
