Activity can not find the Sub in the service

[PowerShell]

hi
this is a similer for what I need, I just can not post the entire program
I need to have the Event in a service and can be called from the Activity

in the log it say that it can not find the SUB
what I am missing

I know that if I declare the timer and inilize from inside the service will work fine, but I have to do it in this way
please check the attachment for more info

Are you looking to call a sub in service from an activity if so its easy use
Callsub(serviceobjectname,"subname")
You have similar methods if you need to pass params.
