How to show different Thank You message based on a condition?

i am confused about how best to do this. i have designed my form in such a way that users scroll down to select their preferred option...see the link here https://form.myjotform.com/63126239346557

now, i want to make sure that if someone selects say mom of the bride speech, that user gets to download a word document attachment right on the thank you page....customers want this done so please help

There is an option to create multiple Thank You pages and to show them conditionally. I think you could add different download links to the pages. 

Please look through the following guide: How-to-Change-Thank-You-Message-Using-Conditional-Logic
