[nant-dev] Error running task containing <script>

[Tomilchik L. <leo...@ca...>]

Hi,

(below all directory names are replaced with (LT: took out the name)
which is the same dir on my local drive)

I get an error running the following:
	<target name=3D"test">
		<echo message=3D"executing target 'test'"/>
		<nant buildfile=3D"(LT: took out the
name)\globals.build"/>
		<nant buildfile=3D"(LT: took out the
name)\globals.build"/>
	</target>

The buidlfile globals.build contains the following <script> task:
    <script language=3D"VB">
        <code>
			<![CDATA[

stdout.

String
						Get

						Set(ByVal Value As
String)
							fName =3D Value
