mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of bind variables

So I have this massive headache inducing query that I need to perform involving 65 form inputs needing to be injected into a database using mysqli prepared statements.

The issue I'm running into is that it says the # of variables I am attempting to call

bind_param
on does not match the # of "s"'s that I am using. I counted a dozen times and do not see where I am going wrong here. There are 65 variables, and 65 "s"'s.

Can anyone see something I'm missing? Or am I perhaps using the bind_param method in an incorrect manner?

// Preparing our query statement via mysqli which will auto-escape all bad characters to prevent injection
$query3 = 'INSERT INTO datashep_AMS.COMPLETE_APPLICATIONS (

$stmt->execute();

Answer

The characters in the string should not be separated by commas:

$stmt->bind_param("sss...", /* variables */);

You can see this format demonstrated in the examples on the manual page.
