compiler error BC30451 but not when pre-compiled

[Tony]

Hi,

when i run this code below, i get the error:Compiler Error Message: BC30451:
Name 'check' is not declared.
but if i compile it in advance like this:aspnet_compiler -p
"c:\inetpub\wwwroot\resintra" -v / c:\compiled\resintra -f
or if i run it within Visual Web Developer (Cassini), in both cases it works
without error!!

Any idea?
Thanks T.
