Set the name of the document when it is created - google-apps-script

Question

I am trying to edit this "Generate from Template" script. What the script does is based on a template it inputs information from a Spreadsheet to a Document. I like how it works except that it just names the document a copy of the template then the row number. This isn't very efficient for what i am trying to use this for. My question is how would i be able to do one of these options:
A: Have the name be based on a certain Cell in the row. For example, there is a column named Claim # and Department. I would like both of those to make up the title for each document. The document would be: " {department name} {claim #} " based on the information in that column in that row that was exported.
B: Have a box to put in when generating the document that asks what i want the file to be named.
Thank you for your help!
PS: If it is needed the columns that i would use for the name of the document are: column E then Column D.
This is the code: (I did not make this, i found it in the gallery.)
function generateDocument(e) {
var template = DocsList.getFileById(e.parameter.Templates);
var row = e.parameter.row
var myDocID = template.makeCopy(template.getName()+" - "+ row).getId();
var myDoc = DocumentApp.openById(myDocID);
var copyBody = myDoc.getActiveSection();
var Sheet = SpreadsheetApp.getActiveSpreadsheet();
//Browser.msgBox(row);
var myRow = SpreadsheetApp.getActiveSpreadsheet().getRange(row+":"+row);
for (var i=1;i<Sheet.getLastColumn()+1;i++){
var myCell = myRow.getCell(1, i);
copyBody.replaceText("{"+myCell.getA1Notation().replace(row,"")+"}", myCell.getValue());
}
myDoc.saveAndClose();
//var pdf = DocsList.getFileById(copyId).getAs("application/pdf");
//MailApp.sendEmail(email_address, subject, body, {cc: carbonCopy, name: senderName, htmlBody: body, attachments: pdf});
var app = UiApp.getActiveApplication();
app.close();
return app;
}
function getTemplates() {
var doc = SpreadsheetApp.getActiveSpreadsheet();
var app = UiApp.createApplication().setTitle('Generate from template');
// Create a grid with 3 text boxes and corresponding labels
var grid = app.createGrid(3, 2);
grid.setWidget(0, 0, app.createLabel('Template name:'));
var list = app.createListBox();
list.setName('Templates');
grid.setWidget(0, 1, list);
var docs = DocsList.getFolder("Templates").getFilesByType("document");
for (var i = 0; i < docs.length; i++) {
list.addItem(docs[i].getName(),docs[i].getId());
}
grid.setWidget(1, 0, app.createLabel('Row:'));
var row = app.createTextBox().setName('row');
row.setValue(SpreadsheetApp.getActiveSpreadsheet().getActiveRange().getRow());
grid.setWidget(1, 1, row);
// Create a vertical panel..
var panel = app.createVerticalPanel();
// ...and add the grid to the panel
panel.add(grid);
// Create a button and click handler; pass in the grid object as a callback element and the handler as a click handler
// Identify the function b as the server click handler
var button = app.createButton('Submit');
var handler = app.createServerClickHandler('generateDocument');
handler.addCallbackElement(grid);
button.addClickHandler(handler);
// Add the button to the panel and the panel to the application, then display the application app in the Spreadsheet doc
panel.add(button);
app.add(panel);
doc.show(app);
}
function onOpen() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var menuEntries = [{name: "Generate from template", functionName: "getTemplates"}];
ss.addMenu("Template Generator", menuEntries);
}

The makeCopy method includes the possibility to give a name to the copy, the autocomplete shows it clearly
So in your code you could do it like this :
function generateDocument(e) {
var template = DocsList.getFileById(e.parameter.Templates);
var Sheet = SpreadsheetApp.getActiveSpreadsheet();// I moved this line a bit to have Sheet available
var row = e.parameter.row
var myDocID = template.makeCopy(Sheet.getRange('E'+row).getValue()+'-'+Sheet.getRange('D'+row).getValue()).getId();// this is a basic implementation to compose the name with content of column D and E separated by a hyphen... customize it the way you want.
