What steps from the "Richtig debuggen" process have been completed in attempting to identify the error in the script?

The issue in the script may be due to a syntax error or a logical error. To solve this, we need to carefully review the code, check for any typos, missing semicolons, or incorrect variable names. Additionally, we can use debugging tools like var_dump() or echo statements to track the flow of the program and identify the root cause of the error.

```php
<?php

// Sample code snippet with a syntax error
$variable = 5
echo "The value of the variable is: " . $variable;

?>
```

In this example, the missing semicolon after `$variable = 5` is causing a syntax error. By adding the semicolon, the script will execute without any issues.
