Как сделать что бы idx начинал считать с нуля?

Вызов снипета:

<div class="bx-pager">
    [[!getImageList? 
        &tvname=`slider`
        &tpl=`@CODE:<a data-slide-index="[[+idx]]" href="#"><img src="[[+thumb]]"></a>
    `]]
</div>

Результат:

<div class="bx-pager">
    <a data-slide-index="1" href="#" class="active"><img src="...."></a>
    <a data-slide-index="2" href="#"><img src="...."></a>
    <a data-slide-index="3" href="#"><img src="...."></a>
    <a data-slide-index="4" href="#"><img src="...."></a>
</div>

А надо так:

<div class="bx-pager">
    <a data-slide-index="0" href="#" class="active"><img src="...."></a>
    <a data-slide-index="1" href="#"><img src="...."></a>
    <a data-slide-index="2" href="#"><img src="...."></a>
    <a data-slide-index="3" href="#"><img src="...."></a>
</div>

Hi Technomaniak,

I cant read your questtion, but i can read the code you wrote. I assume you're trying to have 1,2,3,4 instead of 0,1,2,3.

please try this output modifier
```
:add=`1`
```
So it looks like this:
```
<div class="bx-pager">
    [[!getImageList? 
        &tvname=`slider`
        &tpl=`@CODE:<a data-slide-index="[[+idx:add=`1`]]" href="#"><img src="[[+thumb]]"></a>
    `]]
</div>
```
I hope I understood your question right.
