One Subpath Error

Hi Guys,

I am a complete noob at coreldraw and trying to self teach myself with no prior training.

I got a macro that calculates area inside a shape. It works great. 

I now have multiple curves that I "combined" what I thought would work. But the macro tells me "The selected curve must have only one subpath. Break curve apart into separate paths"

When I break it apart the macro does not work since its not a contentious closed shape and when I group it it tells me "The selected object must be a curve not a rectangle or ellipse. Convert object into curves before clicking calculate"

I really don't know what to do besides to redraw everything at once and that will take forever for me.

Any help is appreciated.
