Scrape won't work over IWP

[lsmall]

I am trying to "scrape" html source via the web viewer using the following script.

Set Field [Patient::Source; GetLayoutObjectAttribute ("Reach" ; "Content")]

"Reach" is the webviewer object name

This works perfectly when run within filemaker, but when I run it over IWP (where I need it to run), the target field only displays the URL of the webviwer, rather than the source code.

Any help would be appreciated.

Thanks
