Hi
I understand that you are trying to resolve the error while using the NCO block in your Simulink model.
The error you have received suggests that the output data type of the Gain block in your Simulink model is a ‘double’ while the NCO Block expects a ‘built-in’ integer or ‘fixed-point’ data type.
The data types supported for the input to the NCO block are:
int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | fixed point
You can use information overlays in your model to ensure that you are providing an integer input to the NCO block.
In the Simulink Editor, go to Debug -> Information Overlays -> Ports -> Base Data Types, to identify the output data type of the source block and change the output data type of the source block in your Simulink Model from ‘double’ to one of the supported data types.
Please refer to the following documentation for the NCO Block for more information regarding the input port to the NCO Block
Hope this helps!

As I can see from the screenshot attached, you are getting a different error from what you have received earlier.
The error message is asking you to specify the 'Output Minimum' and 'Output Maximum' for the Gain block. To do this, open the block dialog, select the 'Signal Attributes' tab, and specify the minimum and maximum values that the output signal will likely use.
The system is attempting to provide reccomended data types based on the range on the signals and will need the specifications above.

Put in a type conversion block https://www.mathworks.com/help/simulink/slref/datatypeconversion.html
