Ethan,

I am curious why you are using mysqli_stmt_bind_result() on a statement
that is an INSERT query? I don't use mysqli, but as I read the
documentation it seems to me that this method is intended to bind
results from a SELECT query into variables so that you can simply call
mysqli_stmt_fetch() in a loop and have the variables magically contain
the data from the next row.

Perhaps mysqli is confused because you are both mapping data to be bound
(with mysqli_stmt_bind_param()) and to be returned (with
mysqli_stmt_bind_result()) on the same INSERT query?

If you are just trying to insert, you should only need
mysqli_stmt_bind_param() (which, by my count, has one parameter too many
right now in your code) and mysqli_stmt_execute()   (and probably not
mysql_stmt_bind_param() and mysql_stmt_fetch()). See "Example #2" here:
http://us.php.net/manual/en/mysqli-stmt.execute.php

Dear list -

 Here is my code:

$sql3 = "select max(Indx) from Visit3";
           $result7 = mysqli_query($cxn, $sql3);
           $row7 = mysqli_fetch_array($result7, MYSQLI_BOTH);

           $Indx = $row7[0];
           $sql2 =  "INSERT INTO Visit3(Indx, Site, MedRec, Notes,
Weight, BMI, Date) VALUES(?, ?, ?, ?, ?, ?, ? )";

           mysqli_stmt_prepare( $stmt, $sql2 );

           $_POST['Indx'] = $Indx;

           $_POST['Date'] = $Date;

           mysqli_stmt_bind_param($stmt, 'isisiis', $_POST['Indx'],
$_POST['Site'], $_POST['MedRec'],
               $_POST['Notes'], $_POST['Weight'], $_POST['BMI'],
$_POST['Date']);
           mysqli_execute($stmt);

$_POST['Site'], $_POST['MedRec'],  $_POST['Notes'],
               $_POST['Weight'], $_POST['BMI'], $_POST['Date']);
*//The error is in this statement*
          mysqli_stmt_fetch($stmt);
          mysqli_stmt_close($stmt);

*Warning: mysqli_stmt_bind_result(): Number of bind variables doesn't
match number of fields in prepared statement*

Help and advice, please.

Maybe right here there needs to be something?

mysqli_stmt_bind_result($stmt, ?????, $_POST['Indx'], ...

in the statement above you have.

mysqli_stmt_bind_param($stmt, 'isisiis', $_POST['Indx'], ...

what ever 'isisiis' is, you need to put somehting in your
...bind_result() I think.
maybe..

mysqli_stmt_bind_result($stmt, '', $_POST['Indx'],

or

mysqli_stmt_bind_result($stmt, 'isisiis', $_POST['Indx'],

sorry for not a more concrete answer. I am guessing a little. :)

If I had read further I would not have made my post a moment ago. Give Matt here the credit for seeing the forest thru the trees. :)
