Hi,
No luck, there was nothing obviously wrong with any of the links. or the site collections.
Here is how my data connections are set up.
I have a Data Connections folder in my site collection.
I test the connection is working when I create it then I select to convert to udcx.
I find add the file to the others sitting in that folder (most of which are working) ;
I re-publish the form.
I definitely think that for some reason it can't find that file as the others all seem to get picked up okay.
Is there a database list of these connections I can look into ?
Jacqui.
