Passing the integer value of getPage's +pageCount and +page to a snippet

I've been looking all over for the answer to this question with no luck. I need to pass the integer value of +pagecount and +page over to a snippet so I'll be able to calculate rel=prev and rel=next. I tried using the call below, but the value does not pass into the snippet:

[[!PaginationNextPrev? &currenturl=`[[++site_url]][[*id:isnot=`[[++site_start]]`:then=`[[~[[*id]]]]`]]` &totalpages=`[[+pageCount]]` &pagenum=`[[+page]]`]]

can someone point me in the right direction? I assume it has something to do with modx->xxxx but my knowledge of that function is very novice.

Thanks
Chris

Is there some reason you can't use getPage's built-in prev and next links?

Assuming that you can't . . .

The +page and +pagecount placeholders won't be set until after getPage runs.

I think I would create a simpler snippet with its tag below the getPage tag and use it to set my own placeholders:

[[+prevLink]]   [[+nextLink]]

I'd move most of what happens in your tag above into the custom snippet. Something like this:

<?php

$docId = $modx->resource->get('id');
$siteStart = $modx->getOption('site_start');

if ($docId != $siteStart) {
    $pageCount = $modx->getPlaceholder('pageCount');
    $page = $modx->getPlaceholder('page');

    /* Calculate what you want in the prevLink and nextLink placeholders here 
       based on $docId, $page, and $pageCount -- then set them in the 
       $prevLink and $nextLink variables 
    */

    $modx->setPlaceholder('prevLink', $prevLink);
    $modx->setPlaceholder('nextLink', $nextLink);
}

return '';
