Java Script Does not Calculate on Condition; Instead posts the condiotion

    The following form calculates the Profit or Loss on the factors provided in the Script.

    I wanted to add a condition where if the TRADE field is "BOUGHT" then the calculation to attain the Field POINTS should be (exit_rate - entry_rate) and while the the TRADE field is "SOLD" then the calculation to attain the Field POINTS should be (entry_rate - exit_rate).

    Instead the information in Trade Field has no effect but the data provided in "entry_rate" and "exit_rate" but posts BOUGHT in "trade"field.

    Please Help and thanks in advance.
