Sentence: The task XYZ cannot be carried out prior to the tasks XYZ be concluded

Hi guys.
I'm translating a software from portuguese into english. Is the following sentence understandable?
1 - The task %s cannot be carried out prior to the tasks %s be concluded.

*the signal %s is just an character which will be replaced by an information by the software when this message is showed to the user.

My suggestion would be as follows:

The task %s cannot be carried out until the task %s is completed.

:)

One more help, please.
How about these two sentences?

1 - The screen cannot be closed since there are other tasks being performed. Wait for them to finish prior to closing the screen.

2 - The checkout opening function must be registered prior to the the importation takes place.

thanks.
