#include nested too deeply Arduino IDE

Here is the code:

#include "ArduinoIoTCloud.h"
#include "WiFiConnectionManager.h"

const char THING_ID[] = "97e8b9343-d81e-45d7-84bc-61eafe7cd9b7";

const char SSID[WiFi]     = SECRET_SSID;    // Network SSID (name)
const char PASS[NOTYOURS]     = SECRET_PASS;    // Network password (use for WPA, or use as key for WEP)


int Deliveries;

void initProperties(){
  ArduinoCloud.setThingId(THING_ID);
  ArduinoCloud.addProperty(deliveries, READ, ON_CHANGE, NULL);
}

ConnectionManager *ArduinoIoTPreferredConnection = new WiFiConnectionManager(SSID, PASS);

I have a different tab that says #include WiFiConnectionManager.h, and that is where I am getting this error. I copied and pasted the code from a project that I found online. Any help is a appreciated

Could you explain what the problem is?

Please post the error message.

ok. Here is the error message

Looks like WiFiConnectionManager.h includes WiFiConnectionManager.h

yes. if this is a problem then how do I fix this?

DON'T put
#include "WiFiConnectionManager.h"
in WiFiConnectionManager.h.

Why did you use the same name as the library file? Do you not have the library installed?

If I do this thing then I get this error.

I have yet another tab where I put #include <ArduinoIoTCloud.h>

I tried searching for the library, but it came empty

you mean this library? https://github.com/arduino-libraries/ArduinoIoTCloud/blob/master/src/ArduinoIoTCloud.h

That does look like the correct library, but 1: Why are there so many lines of code, and 2, where would I put that library ?

have you tried looking for it in library manager?

alright, it seems like that fixed that problem, but I get another one:

The error pops up where it says const char PASS[] on line 3

It looks like it is seeing this on line 7:
const char PASS[C@s] = SECRET_PASS; // Network password (use for WPA, or use as key for WEP)
Can you not see the 'C@s' characters in the IDE window? If not, they may be representing a non-printable character that you can't see but the compiler can. Try deleting the '[' and ']' and everything between, then type [] back in.

I believe I fixed that problem now, could you help me with this one? I get this error on line 10

THE ERROR IS ON LINE 75.
'ArduinoCloud' was not declared in this scope

If You need the whole error message, please let me know

Were you supposed to put this line in?
`ArduinoIoTCloud ArduinoCloud;'

Look at the examples for the ArduinoIoTCloud library examples to see how the library works.

Looks like you called the variable "Deliveries", not "deliveries".

I'm sorry, I can't find the line where it says `ArduinoIoTCloud ArduinoCloud; in my code
