this is my first post, so i just would like say many thanks at first for this community and programmer. I've some problems to create an availability chart in Business Service Section.
Every time, when i try to apply the example script from documentation in script tab off a service object i get following error. "Internal error occured during: "Update Service check script".

I think this error is responsible, why i didn't get the Chart.

Many thanks in advance to all
