Saving files to a specified folder - google-apps-script

Question

I have a script that uses data from a form and key values to fill out a document and convert the document to a pdf. Now I am having trouble getting that pdf to save to a specified folder in my google drive.
function myfunction(e) {
var docTemplate = "1pKwW-RcjaVV8xmm00hWDx1u2QxzQwaSjPJwVY2ux2nI";
var docName = "Form";
var full_name = "Form";
var targetFolderId = "Work Order Forms";
function onFormSubmit(e) {
var Assign_To_1 = e.value[2];
var Assign_To_2 = e.value[3];
var Timestamp = e.values[0];
var Date_Of_Request = e.value[1];
var Requested_By = e.value[7];
var Principal_Approval = e.value[5];
var Urgency = e.value[4];
var Building_Room_Number = e.value[10];
var Description_of_Work_To_Be_Done = e.value[6];
var Parts_Needed = e.value[8];
var Parts_In_Stock = e.value[9];
var Invoice_Number = e.value[10];
var Completed_Signature = e.value[22];
var Incomplete_Signature = e.value[23];
var On_Hold_Signature = e.value[24];
var Estimated_Hours = e.value[14];
var Number_Of_Employees_To_Complete = e.value[18];
var Budget = e.value[11];
var Follow_Up = e.value[16];
var Overtime = e.value[15];
var copyId = DocsList.getFileById(docTemplate)
.makeCopy(docName+' for '+full_name)
.getId();
var copyDoc = DocumentApp.openById(copyId);
var copyBody = copyDoc.getActiveSection();
copyBody.replaceText('KeyAssignedTo1',Assign_To_1);
copyBody.replaceText('KeyAssignedTo2',Assign_To_2);
copyBody.replaceText('KeyTimestamp',Timestamp);
copyBody.replaceText('KeyDateOfRequest',Date_Of_Request);
copyBody.replaceText('KeyRequestedBy',Requested_By);
copyBody.replaceText('KeyPrincipalApproval',Principal_Approval);
copyBody.replaceText('KeyUrgency',Urgency);
copyBody.replaceText('KeyBuildingRoomNumber',Building_Room_Number);
copyBody.replaceText('KeyDescriptionofWorkToBeDone',Description_of_Work_To_Be_Done);
copyBody.replaceText('KeyPartsNeeded', Parts_Needed);
copyBody.replaceText('KeyPartsInStock', Parts_In_Stock);
copyBody.replaceText('KeyInvoiceNumber', Invoice_Number);
copyBody.replaceText('KeyCompletedSignature', Completed_Signature);
copyBody.replaceText('KeyIncompleteSignature', Incomplete_Signature);
copyBody.replaceText('KeyOnHoldSignature', On_Hold_Signature);
copyBody.replaceText('KeyEstimatedHours', Estimated_Hours);
copyBody.replaceText('KeyNumberOfEmployeesToComplete', Number_Of_Employees_To_Complete);
copyBody.replaceText('KeyBudget', Budget);
copyBody.replaceText('KeyFoolowUp', Follow_Up);
copyBody.replaceText('KeyOvertime', Overtime);
copyDoc.saveAndClose();
var pdf = DocsList.getFileById(copyId).getAs("application/pdf");
var doc = DocsList.getFileById(copyId);
function moveFileToFolder(fileId, targetFolderId) {
var targetFolder = DocsList.getFolderById(targetFolderId);
var file = DocsList.getFileById(fileId);
file.addToFolder(targetFolder);
}}}
Here is my code so far. Everything is working except the saving in a specified folder part. Please help I am very new to this.

Answer 1

See this old post : https://stackoverflow.com/questions/13532114/google-apps-script-addtofolder-adds-to-folder-and-mydrive/13536275#13536275
code is as follows :
function moveFromRoot(){
folder=DocsList.createFolder("MyFolder");
var file=DocsList.createFile('File2', 'Empty');
file.addToFolder(folder);
file.removeFromFolder(DocsList.getRootFolder());
}
but as mentioned in the answer, you can create the file using the folder object itself (folder.createFile('blabla'))
