Custom schedule on every 5 minutes

Custom schedule on every 5 minutes

Hello,

i try to create a custom schedule that runs every 5 minutes daily which is described in this post :
Can I lock a record that is being edited, and restrict more than one user from editing the same record at the same time?

How can i do this ?
I get always errors when i try to create the "execute event"-statement.
I found nothing in the help section.


Thanks in advance.

Horst
