Errors when using Parametric Curve Feature Script

Hello,
I have been attempting to make use of the Parametric curve feature script by Mahir Abrahim & Ilya Baran. I am modeling a parametric Cycloidal disc, and am receiving the following error in the Feature Script Notices.
R = 36
N=21
Rr = 4
E = Rr/2
P = -atan((sin((1-#N)*#t(deg)))/((#R/(#E*#N))-(cos((1-#N)*#t(deg)))))
X = (#Rcos((#t360degree))-#Rrcos((#t360degree)-#Phi)-#Ecos(#N(#t360degree)))*mm
Y = 0mm
Z = (-#Rcos((#t360degree))+#Rrcos((#t360degree)-#Phi)+#Ecos(#N(#t360degree)))*mm
Min t = 0
Max t = 1
Apologies for the poor formatting. The multiplication is bolding parts and I don't know how to prevent that.
Is there somewhere I'm going wrong? I'm sure there's just a small syntax error I made and have yet to notice or something else to that effect, but I've been tearing hairs out over this and any help would be greatly appreciated.

Update: I have found some errors in my equations and have since corrected them. my new equations are as follows
X = (#Rcos((#t360degree))-#Rrcos((#t360degree)-#Phi)-#Ecos(#N(#t360degree)))*mm
Z = (-#Rsin((#t360degree))+#Rrsin((#t360degree)-#Phi)+#Esin(#N(#t360degree)))*mm
The part is now generating, but nothing is being displayed on screen, and I am limited in the number of samples I can set. For some reason I receive an error when requesting anything above 70 except for 71.
