Hi,

I am trying to find my way around the simbiology toolbox. I am modeling exchange between two pools of chemicals, but with the added caveat that I want to include label exchange. Therefore I have 4 pools, and two reactions, but the reactions have the same rates as they are insensitive to the presence of an isotope. I want to include an algebraic rule that pyr_c + pyr_h =1 and that lac_c + lac_h =10. The initial values for the pools are pyr_c=.1 and pyr_h=.9, and lac_c=10 and lac_h=0. When I add a rule using the workspace editor, it looks like the first figure, and error. When I open the Block property editor, the there is no way to edit the definition; it is locked. I am using a demo copy, if that makes any difference. How can I add a rule in the workspace editor?

Thanks
