You have a form variable called 'lpn'. When the dtml method receives the 
form information 'lpn' is already in REQUEST.

It looks like you also have a folder called 'lpn'. This stmt: <dtml-call 
"REQUEST.set('lpn', lpn)">  is causing zope to load a reference to the lpn 
folder into REQUEST.

When you get to the ...createInObjectManager... stmt, REQUEST contains 2 
versions of 'lpn' and the folder version is being used instead of the form 
version.

Try removing the <dtml-call "REQUEST.set('lpn', lpn)"> stmt.
