Help for a simple automation macro

[Nukee]

Hello dear MacroScheduler Community,
I am an absolute newbie with the tool but for simple tasks like creating a short Macro with mouse and keyboard commands my skills suffice. However there is one step in the macro I would like to use where I do not know if and how it can be done. The task is simple enough: the macro should work its way through a list of people by clicking on them and then sending a message to them. Then it should scroll down to the next person an repeat the task. So far so easy, but sometimes in the list there are anonymous people that can't be clicked.
Is there a way to tell the macro to scroll to the next person if the left click doesn't do anything? I suppose one would have to add a string in the macros script?

Greetings, Nukee

Would need to see the interface etc to give us a rough guide to work from.
