Glad you sorted it, Barnum! Of the two examples you had above, the first is better (in terms of accessibility etc.) because when someone clicks that link, the new page opens in the same window. People can then click the back button if they want to return to your site.
In the example that includes target="blank", your page stays as is, but a new browser window opens on top of it displaying the destination page. In this case, the back button does nothing, and that can confuse people. To get back to your site, they have to close the current web page to see your site again. That's why use of target="blank" is discouraged now.
