Concat problems

Hello All, I'm trying to create a report that includes a column that will return a link to the proof of a document. I've been trying to concatenate something like "https://xdomain.com/proof/",{Document GUID},"/",{Proof ID},"/view", but I can't figure out the formatting for the text editor in the reporting tool. This is my first attempt at something like this, so it's very likely that I'm missing something obvious. These are the two attribute fields that I'm trying to concatenate with the URL strings: linkedname=currentVersion namekey=view.relatedcolumn namekeyargkey.0=currentVersion namekeyargkey.1=proofID querysort=currentVersion:proofID textmode=false valuefield=currentVersion:proofID valueformat=HTML displayname= linkedname=direct namekey=ID querysort=ID valuefield=ID valueformat=HTML Kevin Habuda
