BPSK signal

Hey People,

Im trying to mak a BPSK modulator. I have a sequence of 1s and -1s. For

each bit in the sequence, I have specified in the formula node loop a phase of

0 or 180, which i input into a sin wave generator.

Currently it just generates a sin wave using the first phase of the first bit. And

I have no idea why it is doig that, because it is a for loop, and gets a new

phase for every iteration as can be seen in the phase array as shown.

Any help would be very much appreciated.

Thank you.

Seems to be a corollary of this question.
