Hi I am having a problem with a simple ifelse statement, i can feel the answer is staring me in the face but i just cant suss it.
It's an ifelse statement that should increment a var from the current month number to 12(dec) then to 1()jan, another goes from current month no. to 1(jan) then to 12(dec)
What happens however is that it just keeps incrementing or decrementing and breaks the code when Tmonth = < 1 or > 12 when executing monthname(Tmonth)
Here is the code
Thanks in advance
Code:
<%
Tmonth = Month(Date())
tnow = Month(now)
adder= Request.QueryString("calnav")
counted= Request.QueryString("count")
if adder = "" then
counted = "0"
Tmonth = Month(Date()) + counted
Response.Write("loop 1")
elseif adder = "plus" and Tmonth = 12 then
counted = 0
Tmonth = 1
elseif adder = "plus" then
counted = counted + 1
Response.Write(counted & " pos <br>")
Response.Write("loop 2 <br>")
elseif adder = "minus" and Tmonth = 1 then
counted = 0
Tmonth = 12
elseif adder = "minus" then
counted = counted - 1
Response.Write(counted & "neg")
Response.Write("loop 3")
end if
%>
<html>
<body>
<a href="shortcalxp.asp?calnav=minus&count=<%=counted%>"><-- (last month)</a>
<a href="shortcalxp.asp?calnav=plus&count=<%=counted%>">--> (next month)</a>
</body>
</html>
What are you trying to do? The code isn't contained within <% tags, either.

the quotes i forgot to copy out.
When the "-->" (next month) link is clicked the code cycles from the current month number "Tmonth = Month(Date())" (month 9 now) to 12 (December). When Tmonth = 12 then Tmonth should be set to 1 (january). The opposite is supposed to happen when <--last month is clicked and Tmonth = 1, it should set Tmonth = 12 jan to Dec.

For a start it's a bit difficult to make out exactly what you want. I think i have an idea. What happens at the momment?

Yes No
Is this what you want?
Code:
<%
If IsEmpty(Request("m")) Then
TMonth = Month(Date)
Else
TMonth = Month(DateAdd("m",Request("m"),TMonth))
End If
%>
<html>
<body>
<h1><%= MonthName(TMonth) %></h1>
<p><a href="shortcalxp.asp?m=-1"><-- LastMonth</a>
<br><a href="shortcalxp.asp?m=1">Next Month --></a></p>
</body>
</html>
Actually, this is rubbish, forget that.

you're making things much more complex than they should be.
instead of having minus/plus in the link, have the actual month in there...
ASP Code:

Dim calMonth
calMonth=Request("month")
If IsNumeric(calMonth) Then
calMonth=CInt(calMonth)
Else
calMonth=Month(Now)
End If
'.....use calMonth to display calendar.......
'.......
'.......
If calMonth>1 Then
Response.Write("<a href=""?month="&(calMonth-1)&"""><-- (previous month)</a>")
End If
If calMonth<12 Then
Response.Write(" <a href=""?month="&(calMonth+1)&""">Next Month --></a>")
End If

that is spot on. thanks a million. This is what i originally started to make it work with, by only passing a 1 or -1 through the url but got frustrated with it and ended up with the mess i posted before.
There is one thing, i assumed it would be easy to make it jump from dec 05 to jan 06, I tried to add another else if condition but it just seems to be ignoring it, why is that?
I created a var. datum and then added extra conditions to the if / else statement that add or subtract from the year.
But they don't work. I tried to look up how to handle IF AND conditions and followed the example but i cant see why it doesnt work, I would really like to understand why it doesnt work as I want to use similar arguments in the future.
Thanks
Code:
<%
dim datum
datum = year(date)
If IsEmpty(Request("m")) Then
TMonth = Month(Date)
Elseif Tmonth = 12 and m = 1 then
datum = DateAdd("yyyy",Request("m"),"1 " & MonthName(Request("d")) & " " & datum)
Elseif Tmonth = 1 and m = -1 then
datum = DateAdd("yyyy",Request("m"),"1 " & MonthName(Request("d")) & " " & datum)
Else
TMonth = Month(DateAdd("m",Request("m"),"1 " & MonthName(Request("d")) & " " & datum))
End If

have you read my reply at all??

Sorry I missed it, i had a look and i would like it to detect the current month and start from there, then inc / decr from there. I like the fact that you can only go forward from a date.
This is for a small events calander I have been trying to develope, so this variable will be passed in to an SQL query to select the current month and the navigation is to see whats coming up.
Thats why i also want it to jump a year from dec-jan. Will specifying the var type help in any specific way? In my ignorance i cannot see any advantage.
Thanks
