Add variable to print_standard_error ..etc

[Moya]

Hello All,

Is it possible to add variables to a standard error?

for example

I have the standard error as

"You are not allow to post because blah blah"

Now I want to change it to

"You are not allow to post because you are at the IP:xxx.xxx.xxx.xxxx"

==> The IP:xxx.xxx.xxx.xxxx is the variable generated from the php files.

Please show me how to incorporate this one onto vb error message

Thanks
