About snippets

Hi, has anyone ever used of the ivf snippets for convenience? Assume this:

<Code Language="ivf" Kind="Unit"><![CDATA[function $name$()
ssss! Variables    <--------------------TestLine-------------------

! Body of $name$
$selected$$end$
end function $name$]]></Code>

I put 4 blanks (represented as 'ssss' sign) at the beginning of the TestLine and then"! Variables" follows. But when inserting the snippet,  4 blanks are gone and "!" becomes the first character on that line. So how could I reserve those blanks then ?
