I use excel a bit, but I am still learning.

Here is the thing I want to try to do:

I have a product that costs X amount I want the said product to have a 35%
total clear profit after VAT.

I want a cell to have the trade price, the next cell to show the VAT for the
trade price, A cell to show the selling price (with the mark up), a cell
with the VAT for the selling price and finally a cell where I could set the
mark up value in percents. So if I change the percent value in the percent
cell it shows a different value in the selling price?

I wondered if anyone could help me with this?

Any help would be gratefully accepted.
