Hello,

I am a new to force.com and I face a problem.

I have created 1 custom object Reservation with fields field1 and field2.

I want to add a validation rule that will check (at new object creation time) that another Reservation object does not already exist reservation with fields1that has the same vale as the object being created.

I have look at all the formula possibility and I don't see how to make a "find"  request on the existing objec.

Any idea

Thanks in advance for your help
