Hello,  
I am parsing my data with logstash and I want to **add a new field** and I want to get it value from the first variable of a hash list called Tps wich I got it from a split of the message.

I've tried this line ut it doesn't work !!

`add-field => { "my_new_field" => "%{Tps[0]}" }`

this is my full filter

```
filter {
       if [type] == "1" {
             if "Tps:" in [message] {
                   csv {
                        separator => " Tps: "
                        columns => ["Mat","Tps"]
                    }
                   mutate {
                        split => { "Mat" => " " }
                        remove_field => ["Mat[0]","Mat[1]","Mat[1]","Mat[1]"]
                        split => { "Tps" => " " }
                        remove_field => ["Tps[1]","Tps[1]","Tps[1]"]
                        add-field => { "my_new_field"=> "%{Tps[0]}" }
                   }              
      }else { drop{} }
 }}

```

Can anyone help me please 🙂
