Can't use compound Arithmetic VI to add signals

[C-squared]

Please see the attached file

Starting from a blank VI, I:
1. Created a while loop
2. Inserted a signal generator and accepted the default values
3. Copy and pasted that signal generator in the while loop
4. Inserted a Compound Arithmetic express VI
5. Wired the first signal generator to the Compound Arithmetic VI (wire was fine)
6. Wired the 2nd signal generator to the Compound Arithmetic VI and got the error that the source and the sink are two different types

I don't get any errors when using the ADD express VI. Using a pyramid of ADD VI's isn't a good solution, especially when I'll have 8 or more inputs that need to be aded.

Hello,
The Compound Arithmetic node doesn't support 2 and more dynamic data type inputs.
To add more than 2 dynamic data types, you can use the express formula vi and configure up to 8 inputs.

I meant: "To add 2 or more dynamic data types, you can use the express formula vi and configure up to 8 inputs"
