Macro value is name

[CodeScrubber]

I have a macro, MACRO_NAME, that has the name of another macro as its value. I need to construct a build rule based on the value of the of macro whose name is stored in MACRO_NAME. Both are temporary macros

%MACRO_NAME% is "ARCHIVE_DIRECTORY"

The value of the ARCHIVE_DIRECTORY macro is "". I need to perform a step if this is the case.

I have tries variations of:
condition:
[vbld_TempMacroObj("%MACRO_NAME%")]

I get:
Error expanding macros or script in property condexpr: <Error in System (VBScript) script code at Line 21, Column 2 (Object required: '[string: ""]')>

What am I missing?

Apparently the macro value is not an object but a string, so use

[vbld_TempMacro("%MACRO_NAME%").Value]

Wow, that is subtle. Thanks again!

Hopefully, My forehead will heal where I have been bashing it against the wall for the last few hours...
