Error using type too many output arguments

I'm running into the error " Error using type Too many output arguments" when I run the code I've pasted below. I;m not sure what this error means and can't find similar situations online. This is just a snip of the code, the variables not defined in it are defined by user input during a previous part of the code that functions properly. I've bolded and underlined the line getting the error.

%variable setup

if strcmpi(type,'corner')

delta=1

iteration=0

while delta>(10^-6)

L=0

M2=0

A=((19000*B)/(RD))^.8

%equation conditions

if(d*1000<12.5)

return

end

if(D*1000<50)

return

end

if(D*1000>1000)

return

end

if(.1>B)

return

end

if(.75<B)

return

end

if(.1<B<.56)

if(RD<5000)

return

end

end

if(B>.56)

if(RD<(16000*B^2))

return

end

end

%C value equation

if(D*1000<71.12)

C=.5961+(.0261*B^2)-.216*(B^8)+.000521*(((B*10^6)/(RD))^.7)+((.0188+.0063*A)*B^3.5)*(((10^6)/(RD))^.3)+(.043+.08*exp(-10*L)-.123*exp(-7*L))*(1-.11*A)*((B^4)/(1-B^4))-.031*(M2-.8*(M2^1.1))*(B^1.3)+0.011*(.75-B)*(2.8-(D*1000/25.4))

else

C=.5961+(.0261*B^2)-.216*(B^8)+.000521*(((B*10^6)/(RD))^.7)+((.0188+.0063*A)*B^3.5)*(((10^6)/(RD))^.3)+(.043+.08*exp(-10*L)-.123*exp(-7*L))*(1-.11*A)*((B^4)/(1-B^4))-.031*(M2-.8*(M2^1.1))*(B^1.3)

Possibly syntax error. The strcmpi() function is used to compare strings. So, you need to place the texts in double quotes.

%variable setup 
if strcmpi('type', 'corner')
delta=1
iteration=0
    while delta>(10^-6)  
        L=0
        M2=0
        A=((19000*B)/(RD))^.8

        %equation conditions
        if(d*1000<12.5)
            return     
        end

        if(D*1000<50)
            return     
        end

        if(D*1000>1000)
            return     
        end

        if(.1>B)
            return     
        end

        if(.75<B)
            return     
        end

        if(.1<B<.56)
            if(RD<5000)
                return
