Hi dear community,

yesterday I setup my website for "mediaboxAdvanced" because I want to integrae some videos on my site.
While doing this and preparing my template for it I came accros a problem:
I am using the gallary addon to and I have a self-made chunk that is for building the thumbnail view on pages with a gallery.
This chunk build the link and the "ref" attribute to make the piture links ready for being display in Lightbox2 before.
Before they were like this:
```
ref="lightbox[[++album]]"
```
I only added the album number to be able to show more than one album on a page and not displaying all images on the page in one light box.

Now with "mediaboxAdvanced" I wanted/have to surround those addtions to "lightbox" in square brackets like
```
ref="lightbox[1]"
```
But how can I achieve this?
I only found a workaround that is to insert space in the call like
```
ref="lightbox[ [[++album]] ]"
```
Is there a way to escape the square brackets so that they are not interpreted by MODx?

Regards,
Alexander

you can try this:

create a new snippet with name ’brackets’ and this code:
```
<?php
return '['.$input.']'; 
```
and use it this way as output-filter:
```
ref="lightbox[[++album:brackets]]"
```
