Your syntax looks fine, assuming these exist:

[Geography].[State hierarchy].MEMBERS

[Measures].[Test]

I tried it on Adventureworks 2005 changing it slightly to match an existing Hierarchy and Measure and it debugs fine (by pressing F5 in script view under Calculations Tab):

Calculate ;

/* This SCOPE statement defines the current subcube */

SCOPE([Geography].[Geography].MEMBERS, [Measures].[Sales Amount], *);

/* This expression sets the value of the test measure */

THIS = [Measures].[Test] * 1000;

END SCOPE;

I wonder if your [Measures].[Test] measure is a calculation, or perhaps not available to the query parsers for some reason at the run time. In the script view the CALCULATE is the first statement and calculated members are done later on in the calculations script. If you are setting SCOPE before they are defined that might be your problem.

I tried modifying my Adventureworks version to use one of the calculated measures [Gross Profit] and the debug gave me an error that "the member '[Gross Profit]' was not found in the cube when the string, [Measures].[Gross Profit], was parsed."

This leads to an 'END SCOPE does not match the opening SCOPE' error which is symptom of an error in the syntax in the scope. Try your script again but use a Regular measure to see if that is the issue, run it in debug to see what the exact error is.
