Problem with Parametric Curve FS

I'm trying to use the parametric curve FS but have some issues. My variables (N, R, r, E) are set as numbers. I also have the Define Parameter FS set as t. I'm not too sure why it's giving me an error (failed to regenerate). Is there something wrong with the formula I input, like the /1mm part or something else? I attached the info i input into the FS below. Thank you

I think you need things like
cos(#t * radian)
. Also,#x / 1mm
gets parsed as(#x / 1) * mm
which is may not be what you want. Keep in mind though that at the end, you want to end up with distance units in all 3 variables.If
#R
,#E
, etc. are just numbers, then don't divide them bymm
. Everything inside a trig function needs to be an angle and every parameter needs to be a distance. So, something like#R * cos(#t
*
radian) * mm
would be valid, as long as#R
is dimensionless.
