Hi Daniel, that all depends on EA settings. There are multiple options for busy slots calculation. Best regards, Nikola

In my case I'm sure there is an issue. I have a very simple setup => 1 worker / 1 location / 1 service and I set the "Busy slots are calculated by same"  to location but in some cases when I select a serivce in the caleandar it does not show that the slots are busy. In addition I can set a resevration without any issue with the same location but another service. Which shall not be because all services are created with the same location? I did also try to set the the parameter to worker instead of location but I got the same problem. I'm a php designer, how can I help you to identify from where is coming this issue? checking something out of the DB? I'm prety in an hury as the website as almots finished and I need your function to activate the full service. Many thanks in adavnce
