I created two fields when I set-up SFDC and Marketo for Demographic and Behavior scores. They are both number fields and Marketo is mapped to these fields (I did create them first in SFDC). However, for some reason on the contact level whenever marketo pushes over a new score for either of these fields, salesforce pushes back the negative amount.
I can't figure out why it is doing this and salesforce told me to contact my sfdc admin.... which is me.
annnd nevermind. I found out why. The fields on the contact level were set to "read only" and therefore SFDC was syncing back the value of 0.
