I have an array of styles as follows in my index:  
[  
{  
"id": 1,  
"name": "Tailored",  
"product\_style": {  
"style\_score": 0.06710671,  
"is\_tag": false  
}  
},  
{  
"id": 2,  
"name": "Romantic",  
"product\_style": {  
"style\_score": 0.112370689,  
"is\_tag": true  
}  
},  
{  
"id": 3,  
"name": "Punk / Grunge",  
"product\_style": {  
"style\_score": 0.055999716,  
"is\_tag": false  
}  
}  
]

I want to access a particular index of style array in my script.  
I tried something like this:  
script: "doc[styles.product\_style.style\_score].values[1]"

But it is giving null pointer exception. Please help
