[Zope] - I couldn't insert a user submitted multiline text into Gadfly

[Kiss, Arpad]

Hi,
I have an SQLMethod that inserts data into a Gadfly database table. The
datas are submitted by an HTML form, that has a textarea named mDetail.
My SQLMethod looks like this:

insert into mytable '<!--#var mDetail-->'

And it doesn't work for me. I realised that if mDetail has only one line
of text then it works.
I haven't been able to find a solution.
Any suggestion?
Thanks in advance,
