VRML parameters have the following settings:

If the parameter is preceded by	Then
A red X	It cannot be selected as a block input wire
A green checkmark	It has already been selected as a block input wire
An empty box	It has not yet been selected as a block input wire

To select a parameter as a block input wire, highlight the keyword and press Make%20Block%20Input%20button . The selected parameter appears in the Block Input Wires window.
