You are getting that error because you are trying to use a variable 
defined in an equation (ACR1) before declaring it. This is typically 
what happens when you add equations after the other components in the 
simulation. In order to correct the problem, you have to re-order the 
components and place the equation block before the components using 
those equations. (go to Control cards, "component order" tab and move 
components around)

It is generally a good idea to check the component order and put the 
data readers first, then solar radiation processors, then other 
components, and finally the integrators, printers & plotters. You can 
put all equations at the top or try to put them just before the point 
where they are used.
