    May I know is that any field that I can add on a calculator?

    My main purpose is to calculate the postage,

    for example if customer bought 1 - 3 items the postage is $10,

    if bought 4-10 postage is $20.

    That would require embedding a copy of the form's full source into a web page and adding a script to do the requisite calculation.

    If you build the form and explain in detail the amount of postage required, we may be able to provide a solution.
