XPath query problem w-attributes

In a C# app I have an XPath query where I am trying to return a single node
based on the value of 2 different attributes.
The xml looks something like this:

<TESTS>
<TEST SAMPLE_NUMBER="1" TEST_NUMBER="1"/>
<TEST SAMPLE_NUMBER="1" TEST_NUMBER="2"/>
<TEST SAMPLE_NUMBER="2" TEST_NUMBER="1"/>
<TEST SAMPLE_NUMBER="2" TEST_NUMBER="2"/>
</TESTS>


From the TESTS node I am calling the SelectSingleNode() method like this:

XmlNode testNode = testsNode.SelectSingleNode("TEST[@SAMPLE_NUMBER = 1 and
@TEST_NUMBER = 1]");

I keep getting an "Invalid token" exception. What is wrong?

Any help is greatly appreciated.

Does the C# compile?
If the exception occurs at runtime on which line does it occur, the
SelectSingleNode or earlier?
