Question about hyperlinks

Hey guys! Is it possible to make this?

I have a column with service tags like this:

DKP89MN
PQR1J4L

And I want to create hyperlinks for them but using their text like this:

http://www.dell.com/support/home/pro...rt/servicetag/ServiceTag/maintain?show_warranty_modal=true

I've tried this:
=HYPERLINK("http://www.dell.com/support/home/product-support/servicetag/"&A1&"/maintain?show_warranty_modal=true")

And it created the text correctly, but if I click on it, it says that the website doesn't exist.
Is there a way to do it?
