"Command not found" doing a while loop in bash/shell

Code:
i=0
numberofproducts=${#urls[@]}  #gets number of entries in array called "urls"
numberofproductsminusone=`expr $numberofproducts - 1`   #-subtract by one

while [$i -lt $numberofproducts]
do
	wget ${urls[$i]}
	 i=$(( $i + 1 ))
	sleep 10
done


I'm getting an error

./scrape: line 22: [0: command not found


that line corresponds with the "while" line.

Could anyone help me with this ? I googled but none of the examples I found were relevant to this.

NAME
urls.txt - URL database for regression testing INTRODUCTION
The urls.txt file is installed by default in /etc/siege/urls.txt. When siege is invoked without a command line reference to a URL, then by default it looks for urls in that file. The advantage of using the urls.txt file is two-fold: One, it frees you free retyping a url with every invocation. And two, it allows you to conduct full site regression testing. When the urls.txt file is used, siege reads all the urls in that file into memory and runs through the list in one of two ways, sequen- tially or randomly. The default run is sequential from start to finish and back again until the --reps or the --time option has been satis- fied. With the -i/--internet option selected, siege runs through the file randomly simulating the stress applied by a community of inter- net users. The -f/--file option allows you to select a file other then the default urls.txt file. You may also instruct siege to use a different file with the "file" directive in .siegerc, i.e., "file = /usr/local/etc/urls.txt" You may set and reference variables inside the urls.txt file. All variables must be declared BEFORE they are referenced. Variables are declared with the "=" operator, VARIABLE = VALUE. They are then referenced inside $() or ${}, example: $(HOST), ${HOST} HOST=joey.joedog.org http://${HOST}/browse.jsp?size=5 http://${HOST}/admin.jsp?name=ralph EXAMPLE FILE
This is an exmple urls.txt file. Lines beginning with a hash (#) are comments and ignored by siege. # # Example urls.txt file # URLs database for siege # http://www.haha.com/index.html http://www.haha.com/howto/index.html http://www.haha.com/cgi-bin/howto/display.cgi?1013 www.haha.com/cgi-bin/fm.cgi?first=j.&last=fulmer https://www.haha.com/index.shtml https://www.whoohoo.com/my_whoohoo.jsp # POST data requires a POST directive www.haha.com/cgi-bin/foo.cgi POST first=bart&last=simpson www.haha.com/hoho.jsp POST name=jeff&pass=secret # POST the contents of a file using the # line input character "<" http://www.haha.com/my.jsp POST </home/jeff/data.txt AUTHOR
