Hi all, I have set up a category of items to display in a 2 wide format.

The 1st and 2nd item display perfectly fine, however the 3rd is missed but the 4th takes its place

Here is the code:
<%
If Request.QueryString("category")>0 Then
		Set CatItins=oConn.Execute("SELECT * FROM itinerary WHERE brand_ID='"&SubDomain("brand_short")&"' AND itin_depdate>#"&NOW()&"# AND itin_type="&Request.QueryString("category")&" AND itin_live=TRUE ORDER BY itin_depdate")
%>
							<table width=1000 border=0 cellpadding=0 cellspacing=0>
								<tr>
									<td width=1000 height=56 bgcolor=white valign=top colspan=3>
										<table bordercolor=<%=BGColor%> bgcolor=<%=BGColor%> border=3 cellpadding=0 cellspacing=0 width=1000 height=50>
											<tr>
												<td>&nbsp;<font class=menu size=5>&nbsp;//&nbsp;<%=HomeRow%></td>
											</tr>
										</table>
									</td>
								</tr>
<%
		Count=1
		Do Until CatItins.EOF
		If Count=1 Then
%>
								<tr>
									<td height=20 colspan=3>&nbsp;</td>
								</tr>
								<tr>

		ElseIf Count>2 Then
			Count=1
		End If
		CatItins.MoveNext
			Loop
%>
									
								</tr>
							</table>
<%
End If
%>

Open in new window


I believe it would have to do with this section:
<%
			Count=Count+1
		ElseIf Count>2 Then
			Count=1
		End If
		CatItins.MoveNext
			Loop
%>

Open in new window


however I dont know how to fix it :(

Help please!

>ElseIf Count>2 Then

should be:
ElseIf Count>=2 Then

because if you processed item 2, you go back to "col1"

Hi Guy and thank you very much for that, wouldnt that conflict where i already have:
ElseIF Count=2 Then

Open in new window

?

I have tested it and it makes no difference (prob due to the conflict)

actually, you have this p-code:

start_table_output (<table><tr><th> ... </tr></table>)

loop
   if col = 1  do col 1 layout   AND set col + 1
  else if col = 2  do col 2 layout and set col + 1 (which says col3)
  else if col> 2 go to col1
end loop

that makes you skip the 3rd item, as on col2, you should already go back to col1 layout, not to col+1



to make the code more efficient, and eventually allow more columns in the layout without having to code "more", change the code to this logic:
max_cols = 2
col = 1

loop
   if col = 1   do row_start_output (<tr>)
   
   do col_output (<td> ... </td>)
 
   col = col + 1
   if col = max_cols  do row_end_output (</tr>)   AND set col = 1
end loop

if col <= max_cols and col > 1
  while col < max_cols  do   put_empty_col_output (<td></td>)
  do row_end_output (</tr>)
end if

end_table_outputput (</table>)

Open in new window

then, changing from 2 to 5 columns just requires to change max_cols from 2 to 5 ...
which could be dynamic eventually based on browser media size width or so.

hope this helps

Thanks for that, however it was quite confusing in the way you set it out.

All works, thank you
