How can I create an option to say what other is in multiple choice questions?

I have a few questions that provide an Other option but I cant see how to allow the responder to say what their other is which I need to do. 

May we know what form are you referring to?

In the Multiple Choice fields, you just need to select the field and then click the "Add Other Option" text link. Here's a screen capture:

Hope that helps. Let us know if you need further assistance. Thank you.

I thought that’s what I did will check settings as I recall it just said add other option and didn’t mention text

Thanks It’s fine - it isn’t very clear on the new style that you type over the ‘Other’ to enter text but I can see that is how it works
