I am havin an issue with a very compley saketch.
Its a program for a automatic pet feeding system.

im having following kind of errors:

C:\Users\Manuel\Documents\Arduino\Nokia5110Menu2_copy_20221019092448\Nokia5110Menu2_copy_20221019092448.ino: In function 'void loop()':
C:\Users\Manuel\Documents\Arduino\Nokia5110Menu2_copy_20221019092448\Nokia5110Menu2_copy_20221019092448.ino:59:7: error: 'erogate' was not declared in this scope
       erogate();
       ^~~~~~~

but erogate for example can be found below in the code as void erogate() {.....}

i checked all curved brackets and can't find errors of that kind.

here the link to the full .ino file:
code in the post below

2

Please show your full sketch.
Nothing can be said without the code

3

code can be downloaded on the link ... its big..

4

Do not force the others downloading stuff from external link.
Please insert the code in the forum with code tags.

5

Please post the BIG code in code tags.

I bet the OP defined the function erogate() inside loop().

Do you know what scope is talking about?

See if you can read about variable scope - that will help you help yourself.

op look at void udateFeeding() { where is the closing }?

Use Auto format, OP.

Issue solved quickly with the posted code. Thanks.

And that's not BIG code.

... next...
The function name is

but it called as

Your code contains a lot of errors...

Your sketch contains a number of syntax errors.

To start with in the editor enter CNTL-T - this will indent the code, and if you scroll down you will see missing }'s. This will solve the original problem.

Beyond that there are also a number of spelling mistakes as noted above.... just fix one at a time.
