Lotus Notes Formula

Hi,
 I wonder why what's happening with this codes.. it's an old program. ( it allowed duplicate booking/clash time)

@If(ResourceType="1" & Capacity="";@Return(@Prompt([Ok];"Error";"You must enter the number of attendees before you can find a room."));ReserveDate="" | TimeRange=""; @Return(@Prompt([Ok];"Error";"You must enter a valid Date and/or Time before you can find an available resource."));ResourceCategory="";@Return(@Prompt([Ok];"Error";"You must choose a Resource Category. If one is not available, there may be no resources available for the selected site."));"");
@Command([ViewRefreshFields]);
@If((@Date(StartDateTime) < @Date(@Now)); @Return(@Prompt([Ok];"Error";"You cannot reserve a room for a date which has already occurred."));"");
Keyarg:="CN=*/"+@If(ResourceType="1";"O="+Site;"OU="+ResourceCategory+"/O="+Site);
ResNameCheck:=@If(ResourceType="1";@FindFreeResource(Keyarg;ResourceType;StartDateTime;EndDateTime;Capacity);@FindFreeResource(Keyarg;ResourceType;StartDateTime;EndDateTime));
@If(@IsError(ResNameCheck);@Return(@Prompt([Ok];"Error";"You received the following error when trying to find a resource: "+ResNameCheck));"");
FIELD ResourceName:=ResNameCheck;
FIELD ResourceName:=@If(ResourceName="";"No resource/room found for times and/or capacity requirements.";ResourceName);
@Command([ViewRefreshFields])

I have no context. I don't know if this is a button, an agent, an action, or something else. I don't know you fields.

It looks like it is a customization to either a meeting form in a mail file, or a resource reservation database, EIther way, it doesn't prevent double-booking so much as it just checks for an existing freetime entry for a "range" of resources. If freetime is out of date or freetime booking is not set up correctly, it won't work. You can see whether it is booking free time correctly by doing a lookup for the specific room, and see if blocked ranges exactly match reserved times.

(I'm not 100% certain of this -- the operation of the freetime system in Notes is a black art, and resources and rooms within that is a blacker art. WHat I've said is based on what I've observed in Domino behavior in t he past.)
