Update contact property

Hi there,

I have set up an automation that run when a form is filled in. Within that form there is a number field that via integration with CRM is send to a custum field (payment amount) in the contact.

Now, whenever I fill in another form for this contact, I want to add the value of the number field to another custom field (total revenue). I want to do that with an automation.

So, when a form is filled in, a tag is applied. The tag is the trigger to run the automation. In the automation I run a update contact property, which update the custom field (total revenue). This field is a number field, which allows me to add value, replace value or substract value. But only with manually entered value. And not with a dynamic code (in this case I want to call the custom field (payment amount) to be added to the custom field (total revenue).

How to solve this properly?
