Forum OpenACS Q&A: Re: "Logged In?"-Datasource and Template

Thanks again for the instant answer. I found that procedure (wow, haven't used that word for a while ;) exactly where u said it would be.

But me being an absolute newbie to TCL, I have no idea how I'm supposed to call it.

I tried just writing [ad_get_user_info] into master.tcl, but that supplies me with Request Error:

invalid command name ""
    while executing
"[ad_get_user_info]"
    ("uplevel" body line 107)
    invoked from within
"uplevel {

How do I do that right? Do I have to give any params or have to do an import of some kind?
