Calculation based on Freight Order Type

Hi,

I have a Base freight charge in my Calculation sheet.

The requirement is,

For a Particular Freight order type alone, the Base freight charge should be doubled.

For ex :

For Ex : If the Base freight Charge is USD 20,000 & freight order type is "XYZ01", then the Base freight charge shoul be doubled and displayed as USD 40000 in the same line.

In case if the Order type is something else, Base freight charge should be displayed as USD 20,000 itself.

How this can be achieved?

Please feel free to ask for additional details.

Thanks,

Michael.
