Use a Write (Value library) block as an interface between the Database and the Optimizer (Value library). Follow these steps:

  1. In a Write block, select the Database and table with the variables for the Optimizer.
  2. Drag the clone of the preview table from the Write block to the Optimizer once per variable in the Optimizer.
  3. Set the row and column in the Optimizer for the table. Remember that these are 0 based references (the first row and column are numbered 0).

When the Optimizer changes the variables, they will automatically be changed in the Database.
