How to do addition in my email's html?

[fca206]

For various reasons, we need to build our emails in another platform, and add the HTML to HubSpot as a new email template. I've got dynamic URLs in these emails, that are pulling a personalization token into the URLs, and it is working great! The problem is, I actually need that value PLUS 1.

So, the personalization token pulls a "5" in (as an example), so the value that I actually want to use in the URL would be "6". Does anyone know of a way for me to do this? Below is the script in my email that populates the URL. You can see the personalization token. I essentially want to increase that value by 1.
