What exactly do you need to do?? The way you presented your code here, is the way to go. That is, after executing your code, strBook and strPage will contain the expected values (133 and 16).
What do you need to do with them afterwards? What do you mean with a Selecet statement? Related to a database query, or to a Select Case statement? If the latter is true, you can't use a Select Case statement for more than one variable, so you'll need some nested If / Then statements.
Elaborate some more on what you need to accomplish, so we can help a bit more.....
