How to use Value as input to calculations in modelbuilder

I have several tables with four feature classes and the areas they are covering plus a total area. I want to calculate how many percent each feature class covers, so I've made a model where I extract the area-values with "Get Field Value". The output is then the value contained in a green oval. But I can not find out how to use these values in a simple percent calculation, either with "Calculate Value" or Calculate Field". When I use "Calculate Value" I can see that it collects the right values, but it outputs nothing.

How do I use the values in a calculation? They are named "Value", "Value (2)" and so forth.
Thank you in advance for any inputs!
