Trying to get a curve to spiral onto itself with vex using the cross product No success

I dont know what im doing wrong i have spent over an hour trying to figure out why it isnt spinning when i scrub my channel float. Any help would be highly appreciated

Hi Hunter,

you would probably use the "orient along curve"-node instead, it also happens to offer rotations. However, if you want to do it in VEX you could try:
 

float freq = chf('frequency');
float sc = chf('scale');

float u = vertexcurveparam(0, i@vtxnum);

float amount = u * (1.0 / freq);

matrix m = ident();
rotate(m, amount, v@N);
scale(m, sc);

v@P += v@up * m;
