conv.close('your number is '+ numr);
});
// Set the DialogflowApp object to handle the HTTPS POST request.
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);

There are a number of issues with your code that make it difficult to understand exactly what you're doing. However, there are a few things to note. I'm assuming you're using JavaScript here.
You have a syntax error in how you are using else. The else statement should be followed by an execution block. You look like you're following it with a condition. Perhaps you are trying to use else if there?
conv.ask is a function. You're then assigning a string to it which would remove it as a function. I don't think this is what you mean to do here.
In the Intent Handler for the "done" Intent, you're not sending anything back to the user using the conv.ask() function since you just removed that as a function.
Setting a global variable does not guarantee the value of it will be preserved in between Intent Handler calls. If you want a value saved during a conversation, you should use a Context or conv.data or other means.
