Trouble creating a 3d surface from splines

[acp693]

The attached file is part of a bigger model I'm building. Can anyone tell me why I'm failing to create a surface between all 4 splines?

The function I'm trying to use is: 'Fill Boundary Curves' in the Surface WB. But I get the error message 'Curves are Disjoint'

Any help greatly appreciated.
