Error: expected identifier before '(' token appearing 13 times - c

Question

I know this is not exactly a "question" but I have tried my best to present neatly as possible.
I keep getting this error:
Error: expected identifier before '(' token for 13 times.
I've checked if I
1) have extra/missing any parenthesis
2) added/missed any semicolons
3) Missed any header files
In function 'goToFloor':
Line 86|error: expected identifier before '(' token

I've included the whole code and not just where the errors happened as I have a feeling the errors are not in them

Answer 1

These errors are frequently around constructs like this:
(*elevator).(passenger)=CAPACITY;
prog.c:88:25: error: expected identifier before ‘(’ token
(*elevator).(passenger)=CAPACITY;
^---------Error Here
That is a very strange and obtuse, and incorrect, way to use a structure.
What follows the . must be a field of a structure.Trying to use (parens) means that it is an expression to be evaluated.But an expression is not valid here, it must be a field-name.
This should be:
elevator->passenger = CAPACITY;
