I'm inconsistenly getting complaints from customers that while attempting top fill their shopping cart, certain products will return the following error
Product ID must be numeric
They'll have either 2 or 15 items already in their cart (it's never consistent) and those items all go in fine. Just one certain item always returns that error message.
I have attempted to get the same error on my end, to no avail. I'll try the exact same product as them, and it will always go in my cart fine. It's completely inconsistent, and I can't figure how/why it's happening. The product ID is numeric, it just keeps saying its not and won't let them order it.
I've had several customers try adding something else (works fine), enter the item from a different page, etc. They always get the same error.
Anyone ever run across this before?
thanks

It might be a form-tag issue; netscape/firefox deals with form tags slightly differently than internet explorer, so sometimes you can get away with things when using netscape which cause problems on internet explorer.
try it in internet explorer and see what happens.
my guess would be that this would happen on the shopdisplayproducts.asp page rather than shopexd.asp

I have a new version of the same problem:
I’m trying to set up the demoshop with a MySql database. Everything seems to work just fine except when I try to view the cart I get this error message: “Product ID must be numeric.”
Question: Where is Product ID taken from?
In my database catalogid = numeric and ccode = varchar(50)
Does this error has anything to do with the use of MySql instead of Access?

The problem seems to originate from the server. VPASP support found a solution very quick.  |

Here is the answer I got from Support.
Michael made some modifications that worked.
- - - - - - - - - -
The problem appears to be caused by a server setting that does not allow null characters to be recognized by the isNumeric() function in ASP.
VPASP uses the isNumeric function extensively in security checking so there may be many instances where this error will occur within your site.
I have modified both shopaddtocart.asp and shopproductselect.asp so that the check for numeric characters now reads:
If NOT isNumeric(x) AND x<>"" Then
...
where x is the name of the variable being checked.
Due to this being a server inconsistency, as i stated earlier you may run into this problem again in other areas of the site.
You should be able to modify the line of code where the isNumeric call is being made so that it includes the check for null characters also.
This is the first case we have seen where this problem is occurring, so it is difficult to say how much it will affect your cart.
It may be worth checking with your web host to see if they know of this problem, and if there are any other possible solutions than changing every instance in the code that may throw up this error.
Thank you
Regards,
Michael Dunkley

Hello,
I'm having this same problem in Firefox.
When I change the code to:
If NOT isNumeric(prodid) AND prodid<>"" Then
I still get the same error:
Product ID must be numeric
...and when I change it to:
If NOT isNumeric(prodid) AND prodid="" Then
..I get this error:
Item not found in database id=116, 116
thoughts...?
Thanks in advance,
Steve

Hi Steve,
Perhaps try changing the code to be:
If (NOT isNumeric(prodid)) AND (prodid<>"") AND (NOT isnull(prodid)) Then
If this doesn't work, the quickest way for us to diagnose and fix your problem would be if you could please post us a ticket in our helpdesk with your site's details.
Kind regards,
Claire

Hi there,
The problem is being caused we believe by using the [special_orderbutton] template tag in your tmp_productformat.htm files. This tag can only be used for extended description templates (shopexd.asp) and not for product display templates (shopdisplayproducts.asp)
You need to replace this tag in tmp_productformat.htm file with:
[formatproductoptions sub]
[formatquantity sub]
[formatbutton sub]
and this should fix this problem.
Regards,
Michael
