"Or Statement in And statement" using if operator

Thank you so much for your patience. I haven't really familiar with how to ask a question here.

for k = 3:N-2
if Test(k)==0
    if (Test(k-1)==0||Test(k-2)==0) && (Test(k+1)==0||Test(k+2)==0)
        if count <= 4
            count = 0;
        else
            m= m+1;
            sample1(m,1:count) = Heat_refill(k-count:k-1);
            sample2(m,1:count) = Forward_refill(k-count:k-1); 
            Indice(m,1:count)  = [k-count:k-1];
            count = 0;
        end
    else 
        Heat_refill(k)= Div_Heatload14(k);
        Forward_refill(k)= Div_Forward14(k);
        count = count+1;
    end 
else 
    count = count+1;
end 
end

Here is my exact code.The 'test' data contains non-zero values and zeros, which I want to select and refill certain values based on following flow chart(sorry for cannot insert the chart vertically). But as the result I shown previously, the second if statement didn't do its work.
