Building a Session Variable

[craigward]

Hi,

I can't get my session variable to keep adding the uniqueid's i pass it from a different page.

I am passing values from checkboxes, and submitting those to a page with the following code. I then add a few more ticks to some checkboxes, submit the form and the values from there i want to add to the session. Building up maybe hundreds of concatenated id's

Problem is they don't add the overwrite the previous id's.

Any ideas would be great. Thanks

contactid = Request.Form("uniqueid")
contactid =  contactid + Session("myRunningCount")
	
' Update the Session variable with the new uniqueid's

Session("myRunningCount") = contactid
response.write(Session("myRunningCount"))

That looks backwards to me, I expected:

contactid = Request.Form("uniqueid")
Session("myRunningCount") = Session("myRunningCount") +  contactid 
response.write(Session("myRunningCount"))

Wait until one of the guys who knows what they are doing posts on it, however. I'm just a hack.

It's also a good idea to use the ampersand (&) as a string concatenator. If your variables are numeric then + will yield the sum. If they are strings then you may need to add a separator between the values.

Thanks, It is a string of uniqueid's, i tried the & but it's not working. I just can see where the issue is coming from.

I've been on it all day and now i think i will have to try a different technique.

Thanks

Like I said, I know very little. Maybe:

contactid = Request.Form("uniqueid")

'see what these yield-
response.write(contactid)
response.write(Session("myRunningCount"))

Session("myRunningCount") = CStr(Session("myRunningCount")) & "," & CStr(contactid) 

'how about now-
response.write(Session("myRunningCount"))

In any case, if contactid is numeric and that you want to apply numeric operation on it or with it, you have to convert it to numeric type(s). If it is expected to be an integer, do something like this.
[tt]
contactid = Request.Form("uniqueid")
if isnumeric(contactid) then
contactid=cint(contactid)
else
'decide how you want to handle this case.
end if
[/tt]
Same can be said to Session("myRunningCount").

Thanks guys.

I got it working, it was an issue with the session variable. Because i had done so much testing and didn't clear the session. It couldn't store the values. I renamed the variable to something new and it just started working.

nearly a whole day to figure that out...

Thanks for all you help
