  • y = 1.2999e-0.055x is the formula for an exponential trendline in an Excel chart.
    I want to use it in a condition where Y < 1.2999e-0.055x

    The -0.055x is 'to the power of' but it disappears when posted

    Please can someone show me how do I write it for MFP to interpret it correctly?

  • Hi
    if your MFP session is linked to an Excel spreadsheet where the functions are being calculated you can use the cell values in a trigger expression, for example:
    selections trigger expression cell_Sheet1_A2 is less than cell_Sheet1_A1
