Strategy enable selection disabled

[Marble]

Hello.
I have build strategy using strategy builder and complied without error,
However, if I select attempt to apply with enable selected, once apply button is clicked, enable selection will be unchecked and can not apply.

What would be the solution to apply with enabled selected?

Hello Marble,

Try checking the conrol center log tab or NinjaScript output window for errors. If you press OK and it becomes disabled that means it had a runtime error.
