[ic] Parameters in window.open

[Alexei]

Hi all,

I need to use following code:

 <a href="#" onClick="window.open('[item-field viewpoint]', '3D',
 config='height=600,width=600')"><img src="../images/3d.jpg"
 border="0"></a>

but parameter [item-field viewpoint] not work inside this JavaScript.

(viewpoint - custom field in products.txt)

Any suggestions?

Thanks.

Alexei.
