Trouble with PDO update - php

Question

I am updating a form using PDO's update function. For some reason it is not going through.
Here is code:
$data = "UPDATE insuranceverificationdisclaimer SET InsCoName =:insur, PhoneNumber = :phone, Policy = :policy, InsuredName = :insurname
, MailingAdrs = :mailingad, EffDate = :effdate, ExpDate = :expdate, Email1 = :email, YrVehicle = :yr, Make = :make
, Model = :model, VIN = :vin, TraineeUserName = :user, EmpName = :empname, EmpCoName = :empcomp, AgencyNumber = :agnum
, SignDate = :signdate, AgentName = :agname, AgentPhone = :agphone, AgentEmail = :agemail, Combinedlimit = :csl, bodyinjur = :body
, bodyinjureachacc = :acc
, propertydmg = :prop WHERE TraineeUsername = :user";
echo"1";
$insertdata = $DBH->prepare($data);
$insertdata->execute(array(':insur' => $compname, ':phone' => $phone , ':policy' => $policynum, ':insurname' => $nameofPolicyholder
, ':mailingad' => $newMailingAdrs, ':effdate' => $Policyeffdate, ':expdate' => $Policyexpdate, ':email' => $newEmployeeEmail
, ':yr' => $YearOfVehicle, ':make' => $MakeOfVehicle, ':model' => $ModelOfVehicle, ':vin' => $Vehicleid, ':user' => $username, ':empname' => $EmployeeName, ':empcomp' => $EmployeeCompanyName, ':agnum' => $Agencynum
, ':signdate' => $TodaysDate, ':agname' => $agentname, ':agphone' => $agentphone, ':agemail' => $agentemail, ':csl' => $singlelimit
, ':body' => $bodyinjur, ':acc' => $eachacc, ':prop' => $propertydmg ));
Where , ':csl' => $singlelimit, ':body' => $bodyinjur, ':acc' => $eachacc, ':prop' => $propertydmg begins this is the function that is not working, these are ints in the database and the values are ints. If I remove from the select and the array it will work but besides that it will not.
Let me know if you need anything else!

You should turn on your error reporting as suggested by Michael Berkowski. For now I can only assume that the error is cause by params datatypes not being defined. You can try the following:
$insertdata->bindParam(':insur', $compname, PDO::PARAM_STR);
$insertdata->bindParam(':csl', $singlelimit, PDO::PARAM_INT);
//...bind the other params
$insertdata->execute();
