Trouble compiling tx and rx

Hi guys.
I’m currently trying to do a transmitter and receiver, between 2 photons or argons, with a RFM69 module. Using the example from the library I made communication between the tx and the rx.

The idea for the project is, for the tx to send one message(of 15 possible) and the rx will receive it and execute the function.

This is the code. The last part that is comment is the part that, when uncomment shows error compiling

and appears “Error: Could not compile. Please review your code.”

Could someone give me a lead, of what I’m doing wrong?

Can you post the error message that’s give with SHOW RAW?

One thing that stands out to me is that you’re trying to use and instead of the && operator.

Edit:
Apparently and is legal C++?

Somehow…Today it compile, didn’t change anything…dunno what happened. Thanks for the help! I’ll post if it happens again.
