Oh, now I've got you. This is from a growing cheat sheet I've been making for myself:
Browse - Formatting Cells
Embed: Inside Browse Loop | 2 Set Queue Record
L:IDS='SysID: ' & FORMAT(REQ:ID,@n_10) & '<br /> Ref ID: ' & CLIP(REQ:JobCode) & '<br /> '
In your case you need to do something like this:
L:ContactString=''
IF FIL:Name THEN L:ContactString=CLIP(FIL:Name) & '<br />'.
IF FIL:Address1 THEN L:ContactString=CLIP(L:ContactString) & CLIP(FIL:Address1) & '<br />'.
IF FIL:Address2 THEN L:ContactString=CLIP(L:ContactString) & CLIP(FIL:Address2) & '<br />'.
IF FIL:City THEN L:ContactString=CLIP(L:ContactString) & CLIP(FIL:City) & ','.
IF FIL:State THEN L:ContactString=CLIP(L:ContactString) & CLIP(FIL:State) & ' ' & FIL:Zip.
Then, instead of putting the actual fields in a column, you put in L:ContactString. L:ContactString also has to be long enough to hold all the information, and the downside to this is your headers won't sort the information correctly like it would if you used a field in each column.
