Dynamic Page_Title in Shortcode

I’m trying to do something special with Shortcodes (what else is new) and I don’t have the facility with PHP as I would like, but I believe shortcodes is what will help me. I have a client’s website where they want to sell products, I have created a POST or PAGE for each product. I want to use shortcodes to dynamically build “Add to Cart” (PayPal) buttons that include the name of the Page or Post so I don’t have to create many buttons (like 400+). So is there a way to do something like this?
Create a shortcode in my functions.php like the following:

[Code moderated as per the Forum Rules. Please use the pastebin]

This line:
<input type=”hidden” name=”item_name” value=”Trip Deposit – Page Title”>
Is where I would like to dynamically put the website’s page’s title.

Does this make sense and can you assist?

I’m also wondering if I would have to change the double quotes within the echo to single quotes to make the shortcode work.

Can anyone help me build this shortcode?

Thanks! Chris
