Edit a link in a Task / Workflow email

Hi folks,

We have a broken link in our Sharepoint workflow-generated emails. We're missing a slash between directories. 

The broken link appears in the emails, bullet point 1.

I found where this email is defined in Infopath Designer:

What I'm wondering is how to view/edit the details of the  [%Variable: InternetLink%] to add the missing "/".

Any help would be appreciated, thank you!
