How data is passed to a tool script

I was trying to display the attributes of a notification using a server tool. Here is my tool script.

The issue is that, it is displaying only the SM_OBJ_Name. Other attributes are not getting displayed and no error thrown.

Could somebody please help here?

#!/bin/sh

echo "script started"

echo $SM_OBJ_Name
echo $SM_OBJ_Active

echo $SM_OBJ_ClassName

echo $SM_OBJ_InstanceName

echo "Finished"
