The next step is to enter equations into the model.  From the {Variables} sheet of the equation workbook (here DEMOeqp.xls is shown), click the [2. Put ALL Equations in Model] button and VORSIM will enter all of the equations into the model.  Alternatively, you could click buttons on each sheet one at a time, to put equations into the model workbook (this latter facility is intended more for replacing equations from one sheet if their parameters or structure has been changed).

If there is a problem with the syntax of your equations in the context of a model sheet, you could get an error message.  Otherwise this operation will be completed quickly.  This step can be repeated anytime you change equations but must be done before you configure your model for solution.
