Add two Scores in Marketo

Hi Edward - Oops! Yes that was a typo. Demographic Score - Normalized is based on a field called "Demographic Score," not Behavior Score.

I also incorporated Brigid's advice to use tokens to append the two values, rather than multiple processing campaigns.

Flow:
Change Data Value: {{lead.Demographic Score - Normalized:default=D}}{{lead.Behavior Score - Normalized:default=4}}

I have the scores split up in Latent and Active. These should be combined to a single total lead score. I'm trying to set up a trigger on when one of both scores change to recalculate the total score.

={{lead.Custom Score Active}}+{{lead.Custom Score Latent}}

But the system says only MY. tokens are allowed.

I have set up a service which can be invoked using webhooks to add scores.  This is in beta (can't guarantee 100% availability/reliability), but we can move this into production if there is enough demand.  Here is how you would configure the webhook

Thanks Raj!  I was initially confused by the example in your post as it has hard-coded values; however, when I enlarged the screen shot I was able to see the correct configuration.
