Error in awk

var1=`echo "emp,dept,salgrade" | awk -F, '{print NF}'`
count=1
while [ $count -le $var1 ];
do
i=`expr $count`
tname[$count]=`echo "emp,dept,salgrade" | awk -F, '{ print $(echo $i) }'`
count=$count+1;
echo ${tname[$count]};
echo $count
done

I want to store in tname[1]=emp, tname[2]=dept,tname[3]=salgrade

I am getting error at line

tname[$count]=`echo "emp,dept,salgrade" | awk -F, '{ print $(echo $i) }'`

Here everything thru the loop i need print $1 for first time
print $2 second time .....so on

I am getting syntax error if i do print $($count) or print $(expr $count), tell me how to store them in the way i wanted ...

If there is any other way of doing this let me know .............

thanks !

NAME
tping - Send echo messages to LAM nodes. SYNOPSIS
tping [-hv] [-c count] [-d delay] [-l length] nodes OPTIONS
-h Print the command help menu. -v Turn OFF verbose mode. -c count Send count messages. -d delay Delay delay seconds between each message. -l length Each message is length bytes long. DESCRIPTION
The tping command sends messages to, and collects replies from, a list of nodes, via the LAM echo server. It is similar to the UNIX ping(8) command, and is used as a quick diagnosis of the LAM network. Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it completes, with a delay of 1 second between roundtrips. After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis- tics about all roundtrip messages. EXAMPLES
tping h Echo messages to the local node. tping -v n7 -l 1000 -c 10 Echo 1000 byte messages to node 7. Stay silent while working. Stop after 10 roundtrips and report statistics. BUGS
There is no built-in timeout and tping will wait forever to receive an echo. If no echo is received, due to a dead link or node, tping hangs. Stop the process with a keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of lamwipe(1) is deprecated). SEE ALSO
lamhalt(1), lamwipe(1) LAM 7.1.4 July, 2007 TPING(1)
