Why is my Arduino code not working? Functions

[Blue_Moon2021]

Hi I'm currently doing a bit of a project in my college course and currently using an arduino with a few extra features on it like a ESP8266, LED display etc. Anyways, I'm currently having trouble on what is wrong with me code here. I haven't had trouble with it until I put the two functions calls in setup but I'm having trouble now uploading it. I always figured that the function calls must be in setup but it doesn't seem to recognise it in my code.

And these are the errors I keep getting. I can't seem to find the missing } in the code either.

Move all the '#include' lines to the top of your code.

Then check that "WiFiEspServer server(80);" is the correct code to use for "WiFiEsp.h", my guess is you have it named wrongly, for example should it be "WiFiServer server(80)" perhaps.

I haven't fully followed your code but I suspect you will run into problems by serving the web page in a loop and particularly with the delays in it. Serving a web page repeatedly does not update it in the readers browser. Personally, I would check for the request in the loop() so it isn't missed while in one of the delay routines then when one is received, call a subroutine to publish the web page.
