Modelbuilder - Get Field Value tool won't list fields

[RandyMcGregor_BMcD]

I am using the Get Field Value tool just to provide a way to select a field. (I don't care what the value is, I just want a way to select a field and there is no modelbuilder tool for that that I know of).

In the workspace, the tool works fine and I can selet a field:

 But when I run the model as a tool by double-clicking on it, I am unable to select a field. Is there any way around this, or are there any other suggestions for selecting a field in modelbuilder?

Thank you,
