We have set some fields in mm to calculate the cost of glass for example
((width / 1000) * (height / 1000)) * thickness * number_plates
Where thickness = the actual price per sqm. E.g; 34.25 per sqm
All of that works great however we cannot take any orders under 0.50m2 and i want to be able to add a conditional statement that is hidden saying if the area is less than 0.50m2 the formula will charge 1/2 a sqm2 in price so 34.25/2 = 17.12 and the price can then change upwards if the choose say a W700mm x H700mm.
Who can answer this? please anyone !!!!!
