Help with custom definition discovery

Hello,

I’m created my own definition decovery yaml file for a custom device we use (LCD screen).

All the data is coming in correctly apart from 1.

If I run a snmpwalk it returns these correct 4 values:

snmpwalk -v2c -c publicx 10.10.8.202 1.3.6.1.4.1.33762.7.8.2.12
iso.3.6.1.4.1.33762.7.8.2.12.0 = STRING: "91,117,60,144"

In my /includes/definitions/discovery/gds.yml I’ve added:

    count:
        data:
            -
                oid: rColorReadout1
                num_oid: '.1.3.6.1.4.1.33762.7.8.2.12.{{ $index }}'
                descr: 'Colour Readout'
                index: 'rColorReadout1.{{ $index }}'
                divisor: 0

But instead of the 4 values I see:

Any ideas what I can do?

Thanks
