Hello everyone!

I am confused by usage of simple python script in jpdl.xml file.
For example :
<?xml version="1.0" encoding="UTF-8"?
  <process name="ScriptText" xmlns=" http://jbpm.org/4.3/jpdl http://jbpm.org/4.3/jpdl">

  <start g="16,22,80,40">
    <transition to="invoke script" />
  </start>

<script name="invoke script" var="text" lang="python" g="113,18,104,52">
<text>
*#!/usr/local/bin/python
# coding=utf-8
import sys
print "start test!"
testvar = 2 * 2 + 90;print "testvar=", testvar*
</text>
<transition to="wait" />
</script>
  <state name="wait" g="266,18,80,52"/>
</process>

But I got that StackTrace
### EXCEPTION ###########################################
16:38:14,027 INF | [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.StartProcessInstanceInLatestCmd at 1bae5f5
org.jbpm.api.JbpmException: script evaluation error: NameError: +*name 'testvar' is not defined in <script> at line number 6*+

What is this ? I can`t get the value of this variable!!!
Everyone could help me!?
Andrew
