"Error using Window Document Operator"

I have a 'read document' operator connected to a 'window document' operator connected to the output connection 'res'.  Within the Segmenting Processing subprocess of the window document operator, I attached 'seg' to 'doc'.  It then automatically produces another 'doc' connection and gives me the error:

'Mandatory input missing at port Window Document.document 2.'

It suggests I input an operator that creates a document; when I do, and attach that to the next 'doc' that has appeared, the error message becomes:

'Mandatory input missing at port Window Document.document 3.'

This just keeps going; every time I try to fix the problem by inserting another operator that creates a document, a new 'doc' connection appears and the error message remains, one document number higher than the error message before.  I can't figure out what the problem is; any suggestions would be much appreciated!
