Multiple Section Curves with Metaball


Please I need to set two curves for the metaball path, how can I do it? In the image you can see that metaball is following one curve, the other one is just drew but I want it to follow a second one too. The ideal will be to set a curve for each circle (cylinder).

The curve I am trying to add is in the lower purple box, on the code.

Thanks in advace for your help.
