You can use get_param only to get block parameter values, not their output values (which are computed at every time-step). If you'd like for your GUI field to be updated continuously as the model is running, it is best to setup a PostOutputs method execution event. See Accessing Block Data During Simulation for more information.

get_param() & get_param() are used to read and set the block properties (attributes). No block directly returns its output value using get_param().
get_param('block','Value') run correctly for "Constant block" becuase 'Values' is one of the attribute which is passed before the start of simulation.
To access the output value in GUI use Sinks\To Workspace block which will save the output value to base workspace (after completion of simulation) which can be easily accessed in GUI.
Or, start a event listner as suggested by Kaustubha, which will return the output value during the simulation itself.
