PDFMerge Using Dynamic PDF and XML

[Former Community Member]

Hi All.

I have created a dynamic(7) pdf form and trying to merged some xml with it.
I am using the following:

objIOutputContext = objFormServer.renderForm(
file,
sPreference,
xmlData,
"",
null,
sApplicationWebRoot,
sApplicationWebRoot + "/GetForm",
sContentRootURI,
sBaseURL);

file = RegisterForm_863289.pdf
sPreference = PDFMerge
xmlData = 555666

I have used $record.approved_persalNumber as the binding option on a text field in my pdf form.
The form shows in IE but does not show any of the values which I have added with the xml.
When saving the form from IE and looking at its xml, I can see that my xml string was merged into the form. But for some reason, it is just not showing any value in the text box.

What am I doing wrong?
Thanks
