Can I use a TV to get the values of other TVs on the same page?

I’m using Ditto to generate a json file. Ditto does a nice job of grabbing TV values, but I would also like to create an item in the json file that combines the data from several other TVs on that same page.

My idea was to use an @EVAL binding in the TV, but I’ve hit some snags. The TV default value looks like this:
```
@EVAL global $modx; $params['id'] = '[*id*]'; return $modx->runSnippet('KeywordsAllGenerator', $params);
```
The snippet I referenced (KeywordsAllGenerator) looks like this:
```
<?php
$output = '';

$tvnames = array('keywords_general_q1');
$tvoutput = $modx->getTemplateVarOutput($tvnames, $id, 1);
$keywords_general_q1 = $tvoutput['keywords_general_q1'];

$output = $keywords_general_q1;

return $output;
?>
```
Obviously there will eventually be more TVs in that $tvnames array and I’ll do more with the data -- I haven’t done anything with it yet because I can’t get the basic premise to work. With this code, I don’t get anything. What’s weird is, if I just return $id, I can see the correct ID number for each item that Ditto’s pulling from, so I think the @EVAL statement is correct.

Any suggestions on what I’m doing wrong here?

Thanks!
