    Hi,
    i´ve created my own user variable in LEAP. In this variable i want to link the Capital Cost(U.S. Dollar/MW of production capacity) tab and multiply it by exogenous capacity(MW of production capacity) tab(i wrote the formula with the Branch/Variable builder(Ctrl+B)). But an error message appears everytime: "Reference to unit (usd/mw/u.s.dollar) can not be changed in expression. Expression: Capital Cost[USD/MW]*Exogenous Capacity[MW]"
    And by hitting the results button another error message appears and it says: unknown reference "capital"

    How to solve this problem?

    Best regards,
    Philipp
