Hey everyone,

Im working on a project for school where I have to track when the user enters or leaves a certain area. Im using OwnTracks to get the coordinates to the broker and the node Geofence to get the valeu for "inarea". I have a function to get the coordinates and then the Geofence node. Then I have a function to count the entrys and leaves in the area but it doesnt work.

First function:

```auto
msg.payload={
    "lat":msg.payload.lat,
    "lon":msg.payload.lon,
    "name":"a41774"
}
return msg;

```

Second function:

```auto
var entrada = context.get('entrada')||0;
var saida = context.get('saida')||0;

if(location.inarea == "true"){
    entry+= 1;
    context.set('entrada',entrada);
    msg.count = entrada;
}
else if(msg.payload.inarea == "false"){
    saida+= 1;
    context.set('saida',saida);
    msg.count = saida;
}

msg.payload={
    "entrada": entrada,
    "saida": saida
}
return msg;

```

"true" is a string , that should be `true` no quotes, or just `if(location.inarea)`

Probably should be:

```auto
if ( location.inarea === true ){

```

Note the 3 `=` and, as mentioned by others, no quotes.

Then you don't need another `else if`, only an `else`.
