Hi,
I assume you're referring to an Expression Object. To delete this (and any other object) you will have to make sure it is not being "used" anywhere.
First, you will delete any references to it on the Panels. Then, replace all connections where the Expression object is being used with something equivalent -- e.g., if you have something like:
HyperTrend.trendWidth = Exp1
replace this with a Pot, for instance. Finally, change the Expression object itself so as to not use any datamember from other objects (this is not necessary, but is a good idea since you will know what is being modified), e.g., just put a 0 in there.
You should now be able to delete this. If you however get a message like, "Cannot delete due to dependencies..," go to Obj
ect>>Connection browser and look for what other connections are remaining for your Expression object. Get rid of these.
If I missed your point, write back with more details.. and an example file if possible.
Regards,
Khalid 🙂
