Please post the actual template (html) code for help on this kind of stuff, a lot easier to help you that way (and always cut and past from your actual files - typing in pseudo-code is a real no-no).
But to make a link just write the html for the link...
for example, like this in your second column
<a href=foo.php?DriverID=[blk1.DriverID;]>[blk1.DriverName;] </a>
|
And just a note... you only need the block=tr once in the template for the one block.
