I just checked, and apparently I am using 2.0.3.

Joel Haggar suggested I add 'cd ${PRGDIR}' below line 13 in the ma-start.sh file. Now it works. He said 'this will be included in all new releases of Mango'

$ **cat /opt/mango/ma-start.sh
**```
#!/bin/sh

PRGDIR=dirname "$0"

#log output
exec >${PRGDIR}/logs/ma.out 2>${PRGDIR}/logs/ma.err
cd ${PRGDIR}

Only set MA_HOME if not already set

[ -z "$MA_HOME" ] && MA_HOME=cd "$PRGDIR" >/dev/null; pwd

if [ ! -r "$MA_HOME"/ma-start.sh ]; then
echo The MA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
exit 1
fi

Uncomment the following line to start with the debugger JPDA=-agentlib:jdwp=transport=dt_socket,address=8090,server=y,suspend=y

if [ ! -r "$MA_HOME"/RESTART ]; then LOOP_EXIT=true fi

done

OK, Thanks, I loaded the compatible module's and all is well, Thank You for your timely reply.

I found the answer, (right in front of me!) Thanks anyway...yes, I'm new!

I'm new to this application...can anyone help me with a simple example of how to create a meta point using existing real points.
For example averaging 4 analog points (temperature sensors)

Thank You in advance.
