Hi,
I am receiving strange error from Remove function.
I have sharepoint list, ListEmp.
| Title | Employee | Job_type | Job_profile | Level | Supervisor | StatusEmp | StatusSup | Compliance |
| "Map" | Dulat | Eng | Civil | III | Dulat | Review | Review | 41 |
I have gallery, which shows this list with no filtering or sorting, GalEmp.
| Employee | Job_type | Job_profile | Level | Supervisor | StatusEmp | StatusSup |
| Dulat | Eng | Civil | III | Dulat | Review | Review |
When I try to make function on button.
Remove(ListEmp, GalEmp.Selected)
It gives me the following error:

I cannot figure out what is wrong here.
Can someone help me?
Thanks in Advance!
