Percentage Increase Function


I have a database driven website with products, standard cost, and web cost, which I have calculated the web cost as a 40% increase on the standard cost. I am trying to find a way that I can choose my own percentage increase on a group of products so that I can input into a text box the required percentage increase and get it to apply to the products web costs displayed in the table. Any help would be greatly appreciated.


It’s very similar to the price change question you posted earlier. The answer will very likely also be very similar.
