Not enough input arguments

I am not understanding what is wrong with line 10, which is [a,b] = size(t);
function [ diffVec ] = GlobChiSq( p, t, Co, Diff, y )
% For loop that creates difference vector that lsqcurvefit uses to optimize
% p
%This equation has four parameters: p1, p2, p3, and p4. p1 is k1 (on rate
%constant), p2 is k2 (off rate constant), p3 is the length of the unstirred
%layer (L), and p4 is iN (total current).
l = 0;
[a,b] = size(t);
for i = 1:a
for j = 1:b
[c,d] = size(concentration);
for k = 1:d
modelFun = p(4) * ((1 - calcPinf(p,t(i,j,k),Co(k),Diff)) * exp(-calcLambda(p,t(i,j,k),Co(k),Diff) * t(i,j,k)) + calcPinf(p,t(i,j,k),Co(k),Diff));
l = l+1;
diffVec(l) = y(i,j) - modelFun(i,j);
end
end
end
end

You are calling it as your objective function to lsqcurvefit. The input arguments are specific in all the curve fitting functions.
You need to call it as:
[p,resnorm] = lsqcurvefit(@(p,t) GlobalChiSq( p, t, Co, Diff, y ), startingVals, x, y lb, ub, options)
