var range = context.workbook.worksheets.getItem("Sheet1").getRange("A1:D4");

var sumOfTwoLookups = context.workbook.functions.sum(

    context.workbook.functions.vlookup("Wrench", range, 2, false),

    context.workbook.functions.vlookup("Wrench", range, 3, false)

);

Is it possible to change it similarly vba code

with context.workbook.functions
...<my code>
end with

Thanks.
