Help needed on error!!!!!

Hi guys,

I've got this error expression.. can someone help vet through my script and see what's wrong? thanks.

Script:

function outv = generalPackSort (inputarg, fieldname)

if isfield(inputarg, fieldname)

       for i =1:length(inputarg) -1

           low = i;

           for j= i + 1:length(inputarg)

               if eval (['inputarg ('int2str(j)').'fieldname])< ...

                  eval (['inputarg ('int2str(low)').'fieldname])

                   low = j;

               end

           end

           %Exchange elements

           temp = inputarg(i);

           inputarg(i)=inputarg(low);

           inputarg(low) = temp;

       end

       outv = inputarg;

else

    outv = [];

end

end

Command window:

>> packByPrice = generalPackSort (packages, 'price')

??? Error: File: generalPackSort.m Line: 6 Column: 38

Unexpected MATLAB expression.

The error is in "if eval (['inputarg ('int2str(j)').'fieldname])< ...". But I can't figure out what's wrong.

Ouch! Ouch!

if inputarg(j).(fieldname) < inputarg(low).(fieldname)
