Looks like you're missing a single quote before $InsertSteps and around the two references to $_GET. Also, try escaping your variables first, it's good practice to always escape input prior to making calls to the database. Escaping will help protect your application against malicious attackers that could try to add extra commands to your SQL statement.
Example:
$InsertSteps = mysql_real_escape_string($InsertSteps);
$InsertPersonnel = mysql_real_escape_string($InsertPersonnel);
$InsertTime = mysql_real_escape_string($InsertTime);
$InsertFees = mysql_real_escape_string($InsertFees);
$InsertDocuments = mysql_real_escape_string($InsertDocuments);
$InsertComplaints = mysql_real_escape_string($InsertComplaints);
$InsertOfficeName = mysql_real_escape_string($_GET["office_name"]);
$InsertApplicationName = mysql_real_escape_string($_GET["application_name"]);
$sql1 = "INSERT INTO `tbl_charter`(`steps`, `personnel`, `timee`, `fees`, `documents`, `complaints`, `office`, `service`)
VALUES('$InsertSteps','$InsertPersonnel','$InsertTime','$InsertFees','$InsertDocuments','$InsertComplaints','$InsertOfficeName','$InsertApplicationName')";
