How to access structure elements in the stateflow charts

Hello,

I have created struture called carconfiguration which has five elements( Ato E). and i need to feed this carconfiguration as input to stateflow chart. so after creating the structures def in m file i save and ran the m file so now the CarConfig struct is created. but inside the stateflow chart when try to access the elements of the struture like below,

CarConfig == CarConfig.C(I need the third config so i am using C here) i am getting error as the element C is not found or unresolved elements C.

Can anyone help me how to access the structure elements inside the stateflow charts.

Are you able to provide the structure definition file as well as how you defined CarConfig in your chart?

1. You will need to create a Simulink.Bus with the same layout as the matlab structure.
2. Create a Simulink.Parameter called CarConfig. Set its "Value" property to carconfiguration. Set it "Type" property to the Simulink.Bus created in step 1.
3. In Stateflow, create a Parameter called CarConfig in the Stateflow
