Easy Syntax Question

Question

I have a JavaScript asp page. On that page I have the
following line displayed...
<th scope="col"><A HREF="AddToCart2.asp?<%=
Server.HTMLEncode(MM_keepURL) + ((MM_keepURL!="")?"&":"") +
"ID=" + rsMasterCardList.Fields.Item("ID").Value
%>">Withdraw</A></th>
I only want the "Withdraw" hypertext to be displayed if the
variable rsMasterCardList.Fields.Item("Quantity").Value is > 0.
Java is killing me with all the brackets, parenthesis, and
semicolons. I just can't seem to figure out what goes where. Thanks
in advance for all the help.

That's exactly what you have. I used Response.Write to keep
everything
enclosed, but you could have just as easily left the HTML
outside the server
block.
JScript:
<th scope="col">
<%
if((rsMasterCardList.Fields.Item("Quantity").Value) > 0) {
%>
<A
HREF="AddToCart2.asp?<%=Server.HTMLEncode(MM_keepURL) +
((MM_keepURL !=
"")?"&":"") + "ID=" +
rsMasterCardList.Fields.Item("ID").Value%>">Withdraw</A>
<%
%>
</th>
VBScript:
<th scope="col">
<%
If rsMasterCardList.Fields.Item("Quantity").Value > 0 Then
%>
<A
HREF="AddToCart2.asp?<%=Server.HTMLEncode(MM_keepURL))%><%
If MM_keepURL <> "" Then
Response.Write("&")
End If
Response.Write("ID=" &
rsMasterCardList.Fields.Item("ID").Value)%>">Withdraw</A>")
End If
%>
</th>
> Anyway, thank you. I feel like sending you a tip ($).

There's no need for a client-side function. Your data is on
the server; the
HTML is generated on the server; you output what you need
using only
server-side code. The reason there's so much up there is
because of your
need to preserve the query string. If you were only
presenting a link for
ID with no need to keep the query string, it would look much
simpler:
<th scope="col">
<%If rsMasterCardList.Fields.Item("Quantity").Value > 0
Then%>
<A
HREF="AddToCart2.asp?ID=<%=rsMasterCardList.Fields.Item("ID").Value%>">Withdraw</A>
<%End If%>
