    I have this ASP code

    
<%
sub mysub
mytestvariable = 111
end sub


call mysub
response.write mytestvariable

%>
    Code (markup):
    Why does the above code show BLANK value when I response.write mytestvariable ? Shouldn't it output 111?


    Whats the solution?

    It's because the variable mytestvariable is in a local code block and only has scope in that code block. You need to declare it outside of the block.

    The correct way to do it would be to use a function with a return value:

    function myfunction()
    mytestvariable = 111
    return mytestvariable
    end function

    Response.Write(myfunction())
