Robert, I agree with Miyako - it's the execute on server attribute. The problem is IP vars are specific to the machine so you really don't want to use them in EOS methods unless you know what you're doing. (by that I mean you intentionally want to use the contents of the IP var on the server - not what's on the client machine.)
I'd look at the method that's running on the server and pass the IP vars to the method as parameters. If the intent of the method is to populate the IP vars with lookup data or something you could pass the IP vars a pointers instead. BTW - if you happen to run this code in single user mode it will work fine because in single user mode an EOS method simply runs in a new process and since it's on the same machine it will 'see' the IP vars. That can be quite vexing moving code from a single user dev machine to 4D server. Even more so if it's compiled because then it won't throw the error you encountered - the data just won't be right.
