Hello all and thanks in advance for your assistance
I am having issues with what I thought was how to tell the difference between a number and text by using IsNumeric, however I am finding that for example
Is there something I am missing?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

The IsNumeric function returns a Boolean value that indicates whether a specified expression can be evaluated as a number. It returns True if the expression is recognized as a number; otherwise, it returns False.
<%
Dim x
x=10
response.write(IsNumeric(x
x=Empty
response.write(IsNumeric(x
x=Null
response.write(IsNumeric(x
x="10"
response.write(IsNumeric(x
x="911 Help"
response.write(IsNumeric(x
%>
The output of the code above will be:
True
True
False
True
False
<%
Dim x
x=10
response.write(IsNumeric(x
x=Empty
response.write(IsNumeric(x
x=Null
response.write(IsNumeric(x
x="10"
response.write(IsNumeric(x
x="911 Help"
response.write(IsNumeric(x
%>
The output of the code above will be:
True
True
False
True
False
Thanks for that Manuel
The issue im getting is...
x="all"
response.write(IsNumeric(x
If IsNumeric(x) Then
This is coming true and then proceeding in the IF statement
The issue im getting is...
x="all"
response.write(IsNumeric(x
If IsNumeric(x) Then
This is coming true and then proceeding in the IF statement
The actual Code that is having an issue is:
Request.QueryString("event")="all"
If IsNumeric(Request.QueryString("event")) Then
Hi Ryan, in post 42071145, I am displaying the code that is having an issue... :(
I have just thought of something... Its showing up on a page that doesnt require is... eg http://dev.gptouring.com.a
I have just thought of something... Its showing up on a page that doesnt require is... eg http://dev.gptouring.com.a
Request.QueryString("eventthis should be an invalid statement and your page would have generated an error on screen.")="all"
Microsoft JET Database Engine error '80040e14'
Syntax error (missing operator) in query expression 'event_code=code_short AND event_start>Now() AND code_live=TRUE AND event_live=TRUE AND event_ID='.
as what i guess... from this error, it mentioned that Request.QueryString("event
so you need to have a better error handling in case Request.QueryString("event
I think I have figured it out...
doesnt error... is that because it would see "" OR "?" as IsNumeric?
If IsNumeric(Request.QueryString("event")) AND NOT (Request.QueryString="" OR Request.QueryString="?") Then
doesnt error... is that because it would see "" OR "?" as IsNumeric?
If IsNumeric(Request.QueryStrnope... what if you have this?ing("event ")) AND NOT (Request.QueryString="" OR Request.QueryString="?") Then

I am getting errors on:

Why would this happen?
Im not even asking for Request.QueryString("event

Im not even asking for Request.QueryString("event") on this page...
AND event_ID=
and you should fine that something is missing there
I am now using:
Surely it shouldnt be that hard? should it?
for:
If IsNumeric(Request.QueryString("event")) AND Len(Request.QueryString("event"))>0 AND NOT (Request.QueryString="" OR Request.QueryString="?") Then
Surely it shouldnt be that hard? should it?
for:
AND event_ID=

i would simply use:
to ensure a numeric event (ID) was provided
If IsNumeric(Request.QueryString("event")) Then
to ensure a numeric event (ID) was provided
This isnt even on the IF statement page that it is writing, its complete different section...I think somehow in your codes logic, it hits that line of code and run it, which causing the error and display on your page.
Yeah I a not sure why...
The homepage of the website is first in the hierarchy order and the Query that it is erroring on (the line we have seen
'event=') is after it.
just strange!
seems to be not erroring now, been through alot of pages and all good
