gel("sys_uniqueValue").value not working inside UI Action

[Ajit Natarajan1]

I am trying to implement a UI action (form link) that shows in the Catalog Item form that lets developers preview the item inside Service Portal with following script. However, the gel() reference doesnt seem to work. I have an Orlando developer instance where this seems to work fine. Looking for some guidance.

function previewInPortal(){
    var catItem = gel("sys_uniqueValue").value;
    var url = '/sp?id=sc_cat_item&sys_id='+catItem; // replace dev Id with your instance id
    window.open(url,'_blank');    
}

All suggestions are valid. The issue was resolved after I set the "isolate scripts" to false. I had to make that attribute visible by going into configure > form layout.
