Warnings and errors are presented to the user in different ways by MSMB. The table at the top shows that the user defined two species (a and b) whose expressions involve other elements of the model (k1 and c) not yet defined. MSMB colors the cells referring to undefined elements, and provides error messages (listed in the “Model properties” tab) that explain the errors and warnings in more detail.
