Help with adding tax calculation
I currently have my setup as line1+line 2....... = subtotal + freight = total.
i have my txt box setup so it shows 10% of the total so its included.
What i do want to do thoug is add a tickbox next to the tax box so if ticked it will add 10% to the total and show that 10% and if unticked default then it just shows the 10% of the total.
The reason is some customers i include tax in the total but some clients i tell them price without tax as thats how they expect it.
if someone could assist me with this as im lost i would appreciate it.
