Putting HTML In The Middle Of A Function?

set up a simple Function that allows me to create a thumbnail image viewer with headings and text.

One of the variables is a Hyperlink.

It all works fine but I want the hyperlink to open as a PopUp Window, but not sure how to do it.

My Code

function LoadGallery(pictureName,imageFile,titleCaption,captionText,titleText,textText,titleJob,jobText,title Pricelist,pricelistText)
{
var picture = document.getElementById(pictureName);

[Code].....

but what I want is when you click on the text "Click here to see Gemma's Service Price List" (specific to Gemma of course).

.... her price list opens in a popup?

(If you want to try this Gemma is the Director with the Burgundy haircolour, top left on the page).

P.S. I am using the <div class> and id to pass the variable data through the function and display the enlarged image and relevant text and hyperlink... if that makes sense ?
