have <%option explicit%> at the top of your ASP page ... then if you use a variable without first using this type of statement 'DIM your_Variable' ... it will tell you that variable is undefined.

Thank you for your quick reply.

What I want to do is something like:

if isDeclared(variableName) then
...
else
...
end if

Is there some easy way I can do that?

No, the Option Explicit statement requires that all variables be declared before using them.

There isn't anything like an "IsDeclared" function in ASP.
