Okay, I thought this was VERY simple, but I cannot wrap my mind around what I am doing wrong. echo $_POST['max_id']; *The echo returns the correct result *if($_POST['max_id'] ='') { *This is suppose to run the below query if $_POST['max_id'] is not blank* $max_id = $_POST['max_id']; *Sets my POST value to a variable* $info = "SELECT * FROM payment_request WHERE id = '$max_id'"; *Selects record from my database by the matching ID's* $result_info = mssql_query($info) or die(mssql_error()); *Puts the query results into a variable* $row_info = ifx_fetch_row($result_info); *Makes a row in an array for all the returned fields from my query* $my_info = $row_info['my_value']; <input type="Text" value="<?php echo $my_info; ?>" size="20" maxlength="16" name="my_value"> *However, this box returns no data.* I should be using if($_POST['max_id'] ='') { and notif($_POST['max_id']

be correct.
Can someone take a look at this solution and tell me if this would be a descent solution for his problem? I use this logic all over my code base, let me know if it is efficient, clean, well structured, etc... if ( isset($_POST['max_id']) ) { $max_id = (int)$_POST['max_id']; if ( empty($max_id) ) { die('not a valid id'); # or some other, more graceful, way of catching the error } $SQL = "SELECT * FROM payment_request WHERE id = '{$max_id}'"; if ( ( $result_info = mssql_query($SQL) ) === false ) { die(mssql_error()); # again, maybe something more graceful here } if ( mssql_num_rows( $result_info ) == 0 ) { die('nothing to display'); # again, maybe something more graceful here } else { while ( $row_info = mssql_fetch_array($result_info) ) { echo '<input type="Text" value="'.$row_info['my_value'].
			     '" size="20" maxlength="16" name="my_value">';
} } } -- Enjoy, Jim Lucas Different eyes see different things. Different hearts beat on different strings. But there are times for you and me when all such things agree. - Rush
