Adding more Nodes to the Driver Model

The Calculation node is now dependant on the values of the first two Numeric nodes. So if the value of Input 1 changes from 5 to 7, the result of the Calculation node will change too. The results from this model though are not interesting. We have created a model to simulate times tables.

However if we add more nodes to the model, and more Calculation nodes then the results might be more interesting.

  1. Add another Numeric node to the Driver Model.
  2. Name it Input 3.
  3. Make its value 7. Third Input Third Input
  4. Add another Numeric node.
  5. Name this one Percentage Available.
  6. Give it the value of 0.85. Input 4 Input 4
  7. Attach Input 3 to the Calculation node.
  8. Go into the expression editor and divide Input 1 and Input 2 by Input 3. Modified Expression Modified Expression
  9. Click OK to save.
  10. Add another Calculation node to the workspace.
  11. Name it Available Amount. Second Calculation Node Second Calculation Node
  12. Connect the result from Equation 1 and the value from Percentage Available to the new Calculation node. Connecting More Nodes Connecting More Nodes
  13. Go into the Expression editor and multiply the two values together. Percentage Expression Percentage Expression
  14. Click OK.
