Sorry, it's been a long time since I've done VBscript like this.
Maybe you have better luck trying an VBscript forum. I don't think it's that hard.
But before you do, check this:

And especially step 4. They create an Word document and at text from VBscript. All you need to know now is how to connect it to a button.
I'm sorry but this is as far as my knowledge about VBscript goes ( and that ain't much 😉 )
