I think you want to use "mean" instead of "average" for the summary statistic.

You need to have braces around the average and sum, not brackets
{"average", "sum"}

It's easy to get muddled, because if you specify the input arguments as character arrays rather than strings, then you do need to use curly braces. (Notice the single quotes rather than the double quotes around the arguments.)
load patients
tbl = table(Gender,Age,Weight,Smoker);
tblstats = grpstats(tbl,{'Gender','Smoker'},{'mean','sum'},'DataVars','Weight')
