Parametric curve FS by Mahir

I just recently learned about this feature script and used it to create some spur gears, and it worked great. Now I'm trying to create a parametric curve to make a cycloid gear, the equation I've created a dummy variable t, set it equal to 1, and then inserted a parameter t afterwards, but I keep getting an error code saying "error regenerating." The equations I'm trying to use are :
x=(#R*cos(#t*rad))-(#Rr*cos(#t*rad+atan(sin((1-#N)*#t*rad)/(((#R/#E)*#N)-cos((1-#N)*#t*rad)))*rad))-(#E*cos(#N*#t*rad))
y=(-#R*sin(#t*rad))+(#Rr*sin(#t*rad+atan(sin((1-#N)*#t*rad)/(((#R/#E)*#N)-cos((1-#N)*#t*rad)))*rad))+(#E*sin(#N*#t*rad))
I played around with it a bit and noticed that sin((#t*rad)#N) does not work unless #N=1, but sin(#t*rad) does work. I noticed that if #t is inside of a trig function, the only way it works is if it is not multiplied or divided by anything but 1, and that nothing is added or subtracted from it. Is there anything I could do to get around this?
