You've discovered why I hate concatenating HTML in xTalks. ;)

I've found it far less tedious to just write the HMTL as I want it in 
the final output and use the merge function to assemble the dynamic parts.

For example, you could have this in a field named "template":

<a href="http://[[fld "link"]]" target="_blank ">[[fld 
"link"]]</a><br/><br/>

...and then just use this to get the assembled output:

put merge(fld "template") into tData

Check out the merge function in the RevTalk dictionary.  It's a 
life-saver for tasks like this (and a good many others).
