poll hack display problem

I added poll hack on my vb 1.1.4
everything seems all right e.g. post a new poll,
vote a poll

but I found the position display are not quite correctly

in template 'pollview' find:

<TD COLSPAN="" BGCOLOR="{tableheadbgcolor}" ALIGN="CENTER"><largefont color="{tableheadtextcolor}" class=thtcolor><B>$question</B></largefont></TD>

(give or take)
and replace it with

<TD COLSPAN="$colwidth" BGCOLOR="{tableheadbgcolor}" ALIGN="CENTER"><largefont color="{tableheadtextcolor}" class=thtcolor><B>$question</B></largefont></TD>

the important part is

TD COLSPAN="$colwidth"
