The last post column won't sort in ascending order. On line 333 in the members.asp file(won't pre-format the following code, since it would make users scroll horizontally):
<td align="center" bgcolor="<% =strHeadCellColor %>"><a href="members.asp?<% =strNames %>link=sort&mode=search&M_NAME=<%=SearchName %>&method=<% if Request.QueryString("method") = "lastpostdatedesc" then Response.Write("lastpostdatedasc") else Response.Write("lastpostdatedesc") end if %>"><b><font face="<% =strDefaultFontFace %>" size="<% =strDefaultFontSize %>" color="<% =strHeadFontColor %>">Last Post</font></b></a></td>
The code in red needs to be changed to lastpostdateasc.
Also on line 337 in the members.asp file, the last here date won't sort in ascending order:
<td align="center" bgcolor="<% =strHeadCellColor %>"><a href="members.asp?method=<% if Request.QueryString("method") = "lastheredatedesc" then Response.Write("lastheredatedasc") else Response.Write("lastheredatedesc") end if %>"><b><font face="<% =strDefaultFontFace %>" size="<% =strDefaultFontSize %>" color="<% =strHeadFontColor %>">Last Visit</font></b></a></td>
The code in red needs to be changed to lastheredateasc.
