Form to Text File

I'm going to describe this the best way I can. I have a text file I'm currently using as a template. There are several areas of the text file that I need to change and then I save it and ultimately copy and paste it to a different program. What I'm looking for is having an excel form where there are fields I can type in and when I submit it allows me to download a text file. Most of the text is static and never changes there are maybe 3 or 4 items in the text that changes. I may not be explaining this very well. Thanks in advance.

To help illustrate what I'm trying to accomplish a little better. I've attached a text file. The area that says NUMBERSHERE and TEXTHERE would be what I would want to add to the form. Submitting the form would spit out the completed txt file.

Form looks great. When I submit it opens the folder I specify, but it doesn't create the file.
