What does this mean?

I am trying to compile the following kernel but it gives a weird error. Any help most appreciated.



kernel void Calculate_critvar (int aout_full[][], double orig_y[], double v_alt[], out double critvar<>, out double ubestt<>, int ndstart, int ndend,
    double sumnode, double nodecnt )
    int2 ind = instance().xy;
    int kv = ind.x;
    int j;
    double d;
    double suml=0.0, sumr;
    double npopl, npopr;
    double critParent = sumnode*sumnode/nodecnt;
    double crit;
        d = orig_y[aout_full[kv][j]];
        suml += d;
        sumr  = sumnode - suml;
        npopl = ((double)j-(double)ndstart)+1.0;
        npopr = nodecnt - npopl;
        if (v_alt[j] < v_alt[j+1]){
            crit = (suml * suml / npopl) + (sumr * sumr /npopr) - critParent;
            if (crit > critvar){
                ubestt = (v_alt[j] + v_alt[j+1])/2.0;
                critvar = crit;
