Why Radio Buttons in MATLAB GUI not able to set value of parameter in SIMULINK model?

Hi,

Here is the code I am trying to implement to set the parameter value in SIMULINK model using GUI.

f

unction radiobutton_Callback(hObject, eventdata, handles)

val = get(hObject,'Value');

     if val == 1
       set_param([bdroot '/parameter_name'],'Value',800)   
     end

It gives me following error:

Invalid setting in Constant block 'parameter_name' for parameter 'Value'

Can anyone help me with this?

I also tried to use 'Constant' in place of 'Value' in the statement-

set_param([bdroot '/parameter_name'],'Constant',800)

but then it give this error:

Constant block does not have a parameter named 'Constant'

I do not know, but experiment with

set_param([bdroot '/parameter_name'],'Value','800')

Here the parameter has been changed to string.

I tried using 'Value', but it doesn't work either.

Rinachi: Also pay attention to how you pass the actual value of '800' - it needs to be passed in as a string, not a number.

Thanks Walter and Kaustubha. It works when I use '800' as a string.
