Is there any way to do this? I want just the first 4 children of a section, so I figured I could write

<% if Pos < 5 %>

but it fails, blank screen. It seems like the problem is the "less than" operator since "equals" works fine. Does SS not support "less than" or "greater than"?

No, it doesn't support what you're doing.

The best way to solve what you're doing is to create a custom function for your <% control block, and filter the results using the limit argument to DataObject::get()

e.g.

class Page extends SiteTree {

...

function ChildrenWithLimit($limit = 4) {
   return DataObject::get('Page', "ParentID = $this->ID", '', '', $limit);
}

...

}

Then, you can use <% control ChildrenWithLimit %> in your template. Should you want to override the default of 4, you can use <% control ChildrenWithLimit(8) %>, for example.

thanks, that sounds great, except the children I'm trying to pull in aren't children of the page I'm on. I was using ChildrenOf(page-url). How would I use that in the get function?

Considering you are hard coding the url in the theme then you could hard code this in the code and use the ParentID column in the database and compare it against the ID of the pages url

function ChildrenWithLimit($limit = 4) {
$Parent = DataObject::get_one("Page", "URLSegment = 'page-url'");
return ($Parent) ? $Children = DataObject::get("Page", "ParentID = '$Parent->ID'","","", $limit) : false;
}
