Bad variable error while using arrays

[mohangauns]

when i read values from user in an array, It displays Bad Variable error.
code is given below.

count=0
while [ $count -lt $n ]
do
 read arr[$count]
 count=`expr $count + 1`
done

where n is maximum number of elements in an array.

Which shell did you use for executing that script. I checked it works ok with bash.
