    Or you could get both of them in one snippet and output them together with their li tags, if you want to display them both together. Just surround the snippet call with the ul tags.

      Yes, If you mean "I would use 2 Snippet tags -- one to display each TV, instead of using TV tags"

        Bob, a question. What is the advantage/disadvantage of your code vs the code I had suggested for the TV @EVAL code?

          I'm not sure. My code would avoid having to hard-code the resource ID in the TV and I think it would be easier to implement for non PHP coders (less prone to typos). I think it might be a tad faster, since it would avoid the overhead of parsing and rendering the TV and processing the @eval, but I could be wrong.

            Ah, no, I meant that code as the snippet code.

              [[!GetTvValue? &tvId=`12` &resourceId=`14` &render=`0`]]

              Does the above code go in the Chunk where I previously had 
              [[*projectName]]


              And the below code is used "as is" in a new Snippet.

              <?php
/* GetTvValue snippet */

$rid = $scriptProperties['resourceID'];
$render = isset($scriptProperties['render']) && $scriptProperties['render']);
$tv = $modx->getObject('modTemplateVar', $scriptProperties['tvId']);

if ($tv) {
    return $render? $tv->renderOutput($rid)  : $tv->getValue($rid);
} else {
   return "TV Not Found";
}


              If so, then where do I place the Snippet tag?

              Thanks
                Todd

                The snippet tag can go anywhere you want to show the value of that TV.

                  Then I'm unsure as to where this goes?

                    It goes at the spot you want to display the TV value. That tag, wherever it is, will be replaced by the value of the TV.

                    I'm afraid I can't think of any other way to put it.

                      That's what I thought.

                      Here's where I'm confused:

                      If I place 
                      [[!GetTvValue? &tvId=`12` &resourceId=`14` &render=`0`]]

                      where I want the TV value to appear and if my new Snippet is called, say, 'newSnippet', then how does MODX find/use the 'newSnippet' code if I'm not referencing it somewhere in the Chunk or Template?
