Converting Excel formulas in Numbers

I am new to Numbers and have an Excel Spreadsheet that I've used previously that calculates the best 4 scores from golfers over a 10 week period. In Excel I used =sum(LARGE[e2:n2,{1,2,3,4}]) but when I use it in Numbers I get a Syntax Error message. Is there anyone who can help me convert the Excel formula so that it works in Numbers.
