I'm unable to set the Gain control as a variable. The entire Gain block turns red with an exclamation mark.
Setting the Gain as a numeric value works OK.
Thank you.

It turns red with the exclamation mark because you haven't defined the variable in any workspace that the model can see (typically the base or model workspace) and/or you haven't updated the model since the variable was defined. For example, if the parameter in the Gain block is 'mygain' then define it with a value in the base workspace
>> mygain = 1;
Then update the diagram.
