Need help with creating circular pattern of swept helices for a simple stent model (cylindrical mesh)

I am currently trying to create simple model of a flow diverter stent. My model currently contains two swept helices (one propagating clockwise and the other counterclockwise) that I want to create a circular pattern of both helices around their propagation axis. The pattern should contain ~40 - 45 instances of equal spacing to form something that resembles a cylindrical mesh. There is also a video I found on youtube of someone successfully creating the circular pattern to build a model similar to what I want to make:

 

SolidWorks Tutorial #14: Cylindrical Grid - YouTube

However when try to make the pattern, I get an error saying that it is an invalid feature for patterning and that I should recreate the feature using the geometry pattern option/make sure that the feature is on a single solid body. When I then try to hit check on "Geometry Pattern", I get another error saying the selected features could not be patterned using a geometry pattern! If anyone could help me figure out where I went wrong, that would greatly be appreciated!

 

I have my SolidWorks file attached and an image of the circular pattern shown below.
