javascript errors

hi!
i tried this:

<script type=’text/javascript’>
$(‘#5’).click(function(){
$(‘#give-amount’).val(‘5,00’);
});

$(‘#10’).click(function(){
$(‘#give-amount’).val(‘10,00’);
});

</script>

but i have some errors:
on line1 (<script type=’text/javascript’>)this

Expected an identifier and instead saw ‘<‘.
Missing “;” before statement

And on last line (</script>) this:

Unclosed regular expression
unrecoverable syntax error. (100% scanned).

This script works fine everywhere! but not in my wordpress site.
Maybe for these errors?
