Hi Lara, a scaling rail is going to be difficult to use along a helix, the scaling rail is really meant to be used on a planar rail curve with the scaling rail in the same plane as the path curve. There are some examples in the help topic for sweep.
For making a tapered sweep from a small ellipse into a larger one, you can use 2 profile curves for the sweep, a small ellipse at the bottom and a large ellipse at the top. Then before you do the sweep select both of those as profile curves.
You can also use "auto place" mode for the sweep where you put the 2 ellipses down on the construction plane away from the rail (make sure it's outside of the bounding box around the rail) and sweep will automatically place them for you, like this:
