Scripted field in kibana

Elastic Stack Elasticsearch

Hi Team,

I have been to substract the date value and store the value in the variable defined as " duration" and then check if the value is smaller than 2 then return a value through scripted filed in kibana

` ``
if (doc['request_time'].size()!=0 && doc['response_time']!=0 && doc['response_time'].value.getMillis() > doc['request_time'].value.getMillis())
{
return doc['response_time_milli'].value.getMillis() - doc['request_time_milli'].value.getMillis()= doc['duration'].value.getMillis();
}
if (doc['duration'].value.getMillis() < 2)
{
return doc['duration_2'].value.getMillis() = 1;
}
```

although i get an error

"script": "if (doc['request_time'].size()!=0 && doc['response_time']!=0 && doc['response_time'].value.getMillis() > doc['request_time'].value.getMillis())\n        {\n    return doc['response_time_milli'].value.getMillis() - doc['request_time_milli'].value.getMillis()= doc['duration'].value.getMillis();\n        }\n           if (doc['duration'].value.getMillis() < 2)\n           {\n            return   doc['duration_2'].value.getMillis() = 1;\n           }\n ",
"lang": "painless",
"caused_by": {
 "type": "illegal_argument_exception",
 "reason": "Left-hand side cannot be assigned a value."
}
```
