5 seconds:
while($row = mysql_fetch_row($result)
should be
while($row = mysql_fetch_row($result))

sometimes reading the errors can be tricky. when you see expected, sometimes where it says the problem is, isnt where the root lies. in this case, line 24 is where it went wrong, because line 23 had the error, it continued looking for the closing ) and instead saw { on 24, so it complained thats where the error was, which in a way it is. because you could have put the ) on the next line if you really wanted to.

hi dude

excellent.... can I ask a question however

what is the difference between print and echo....

they seem to do the same thing

drew010

not much different. they can both print things pretty much the same except echo is a void function, where print is an int function, that always returns 1. so for that reason there may be a split second speed difference between the two.
also echo supports multiple parameters.
therefore:
echo "hi", " there", " isnt today a nice day?";
is valid while
print "hi", " there", " isnt today a nice day?";
is invalid and will generate a parse error.

the php manual says for print - outputs a string and echo - outputs one or more strings.

they both support array printing, multiple lines, "here document", variable printing, character escaping, and concatenation.

i guess its pretty much programmer preference which one you use. i suppose echo is one character less than print so if you use it a lot your files will be a tad smaller.
