Variables value

[b00gieman]

Hi,

I have the following code:

ID=Request.QueryString("ID_No")
....
if(....) then
.......
if ID>0 then
   ........
else
    .......
end if

end if

My problem is the following:in the if condition , the ID variable has lost its value.Am I doing something wrong?

Not possible under normal circumstances. How do you know it lost its value.

>ID=Request.QueryString("ID_No")
>if ID>0 then
On the face of these two lines, if ID is not numeric, it would be a runtime error on the server. You have to ascertain this fact to secure the script.

if isnumeric(ID) then
if clng(ID)>0 then 'or simply ID>0, up to you
'etc

else
'determine what you want
end if
