Joseph; Keep in mind that there are two things at work here. The script model and the model the script is manipulating (let's call it the result model). The existence of prefix definitions in the script model does not mean the prefixes are defined in the result model.
It's hard to say without looking at the script, but I think the problems could be resolved by adding a ModifyPrefixes module that defines the prefixes for the result model. -- Scott On Oct 22, 9:48 am, Joseph Shea <[email protected]> wrote: > Hello all.
