Cannot change PREFERENCESURL header text

I have a campaign in which I need users to click the [PREFERENCESURL] and input data into attributes. One of the attributes requires the user to lookup a piece of information from a website so I need to include a clickable link to the webpage either under the header message “Please confirm that the information below is correct and click the “Update” button”, or next to the text for the attribute.

How can I do this?

Attributes strip URL links and I can’t find the file that contains the message: “Please confirm that the information below is correct and click the “Update” button”

Thank you.

@pancakehollow The texts for the “public” pages are in the lists/texts directory, one file for each language.

Thanks - anyway to make text in the text file linkable? I tried using html codes doesn’t work. Thank you.
