  84 This block creates a variable with a drop down, radio buttons, or a button. \
  85 Leave the label blank to use the variable id as the label. \
  86 The value index is the index of a particular choice, \
  87 which defines the default choice when the flow graph starts. \
  88 The choices must be a list of possible values. \
  89 Leave labels empty to use the choices as the labels.
  90
  91 Use the Grid Position (row, column, row span, column span) to position the graphical element in the window.
