Make next/previous buttons: assign floating buttons to specific pages (html?)

[mvdb]

Hello,

I have a Birdseye-themed website (http://graphisch.weebly.com) and I want to put Next/Previous buttons on some of the pages (I'm planning to create at least 10pgs). I already found a html code to make an arrow-left button and an arrow-right button, appearing on every page, hovering in the middle (on the side) of that page. 

(See below this message: what I put on the SEO page.)

My problem now is that, no matter what webpage you're on, the arrow-left will always send you to the same page ('info' page in this case) and the arrow-right will always send you to the same page too ('select' page in this case). Whereas of course I want the arrows to send you to a different page, depending on the page you are currently visiting. 

I could of course make an arrow-left that goes to page 1, an arrow-left that goes to page 2, an arrow-left that goes to page 3, etc... so that I have a different arrow-left and arrow-right to go every page. Each of them would link to a different webpage. But if I would do that, every page would have like 10 different arrow-buttons all on the same place, with a different link. 

So how do I assign an arrow-button to a specific page? If I put the arrows on the SEO page, that means the arrows appear on ALL pages of the website. How can I choose what arrow/button goes on what page?

This is the html I put on the SEO page:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css" integrity="sha384-UHRtZLI+pbxtHCWp1t77Bi1L4ZtiqrqD80Kn4Z8NTSRyMA2Fd33n5dQ8lWUE00s/" crossorigin="anonymous">

<form method="get" action="/select">
<button id="submitselect"><i class="fas fa-chevron-right"></i></button>
</form>

<form method="get" action="/info">
<button id="submitinfo"><i class="fas fa-chevron-left"></i></button>
</form>

Thanks for your help, I hope I didn't explain things too complicated!

(I don't know if maye I should use if/else? I've read about it but I don't know how to apply it in the SEO page)

(or is there a way simpler way?? I just don't know what to call the Homepage and the Contactpage etc... in html language)

Did you add this to Settings>SEO>Header? I wonder if it would work if you add it to the page SEO settings. So, click Pages at the top of the screen, then choose a page name and select SEO Settings. You'll find a header/footer section for each page that will override the SEO code on the Settings page. I imagine you would edit each code to change to which page should be to the left or right.
