# hi everyone, i have a problem with array. in my data i have somthing like this in my array:

# array[1] 0: object name: "ether5" rx-packets-per-second: "2" rx-bits-per-second: "1200" fp-rx-packets-per-second: "2" fp-rx-bits-per-second: "992" rx-drops-per-second: "0" rx-errors-per-second: "0" tx-packets-per-second: "1" tx-bits-per-second: "2768" fp-tx-packets-per-second: "1" fp-tx-bits-per-second: "2736" tx-drops-per-second: "0" tx-queue-drops-per-second: "0" tx-errors-per-second: "0"

as you can see betwhen all words i have dash - exepct "name"  
so for example when i used:  
msg.payload = msg.payload [0].fp-rx-packets-per-second;  
debug say:  
"ReferenceError: rx is not defined (line 1, col 34)"  
how can i fix it ?

use the alternative syntax

```auto
msg.payload [0]["fp-rx-packets-per-second"];

```

put the variable name in quotes in square braces with no dot
