mcode in system generator

Am modeling bpsk system using xilinx-system generator block set. while in mcode block, i had written the matlab coding as

function done = bpskmultiplex(mod_sig, m1, m2);

if mod_sig == 1;

done = m1;

else

done = m2;

end

where 'done' is the modulated output,'m1' and 'm2' are the sine and cosine wave inputs and 'mod_sig' is the modulating signal input. But the mcode block didn't give the output.In the coding I had given "BPSKmultiplex", but at the mcode block it didn't change to "BPSKmultiplex".I think thats why i didn't get output.

Can anyone help me how to change it to "BPSKmultiplex"?
