File Solid Block, applying force error

I have a shape in a file Solid block and I am trying to apply a force to it. The Error is as follows:

['untitled']: The following errors were found in the model untitled.

Caused by:

• ['untitled']: External Force and Torque 'untitled/External Force and Torque' has its follower port rigidly connected to the world frame; it has no effect. You can configure this diagnostic in the Simscape Multibody Configuration Parameters dialog.

I have tried add in another frame to the block to try to distinguish when I want to apply the force but I am not to sure what I am doing wrong
