How do I prepend a static URL with a variable in the data to generate a QR Code?

[mailingsvc]

I need to create a QR code for a URL. http://example.com/<<variable>>

In my data I only have the variable part of the URL and can create a URL for that easily. How to I prepend a static "http://example.com" onto that variable before generating the QR code?

return MakeQRBarcode("http://example.com/" + encodeURIComponent(Field("Name")));
