You can't have a function in a cell then enter something in that same cell

So if you create a 4th and 5th column

to get the Net if you enter something in the total use

=F10/(1+17.5%)

to get the VAT

=F10-(F10/(1+17.5%))

If you put in the Net in F8


then use

=F8*17.5%

to get the VAT

and

=F8*(1+17.5%)

to get the total

Hi all

I have a worksheet like below, It might be easy for some but i'm a bit
rusty.

F8 F9 F10
Net VAT Total

What i need is a function that will allow me to enter a amount in either
Net
or Total and it would work out Vat and either Net or Total depending where
i
have put the amount. Hope this makes sense!

Many thanks

Tina
