Extruded Curves Are Incomplete Objects. Help!

[Sabrina_Haertig]

Hey guys,

I am new to Rhino- I made some lines- extrude crv > and yet the lines and the extruded objects are separate entities. Also, the extruded objects (closed) are showing incomplete in Front perspective (see photo)

What could be going wrong?
