# 0111: Function not found in current scope

Compiler found what looked like a [function](/language/functions.md) call but couldn't find a matching definition in the current scope. It can be either because the function with such name was never declared or declared in a scope of another function.

E.g.

```pascal
function foo

  function bar: int
    return 5
  end
end

int x = bar() // `bar` not found, because `bar is defined and available only in function `foo`
```

#### Possible solutions:

* Check the function name spelling. It is possible that you've used a wrong name:

```pascal
function foo
end

var x = fo() // error, `fo` not found
var x = foo() // OK
```

* Check that the function is declared in either the global scope, or a scope of the current function:

```pascal
// global scope

function baz: int
  return 5
end

function foo
  // function scope

  int x = bar() // OK, `bar` is available in current scope
  int y = baz() // OK, `baz` is available in current scope

  function bar: int
    return 5
  end
end


int x = bar() // `bar` not found
int y = baz() // OK
```
