Help troubleshoot script with RANDOM variable

Whether I use the divide signs / or % it will keep giving me that "usage: sleep time"
error. echo $randnm will not echo anything.

I was sure it worked previously but all of a sudden it doesn't anymore

#!/bin/bash
#
randnm=$[ 1 + $[ RANDOM / 100 ]]
pattsigupd.sh[5]: 1: not found
## rndnum=$[ 1 + $[ RANDOM % 100 ]]
sleep $randnm
usage: sleep time
#
echo $randnm

ozo

What is on line 5 of pattsigupd.sh?

This error 1st appear on the original script below (1st 6-7 lines shown below):

#!/bin/bash
#
# pull updates from central server
#
rndnum=$[ 1 + $[ RANDOM % 100 ]]
sleep $rndnum
#

So line 5 is :
rndnum=$[ 1 + $[ RANDOM % 100 ]]

Thanks, I'll test it out next Tue when back to office.

In the meantime, I have a new requirement in another link below; if you can have a
look at it & provide sort of Shell or Perl script to be run in Solaris 10, will appreciate it:

rndnum=$(( 1 + RANDOM % 100 ))

works fine
