Several ways:
You can tie the two actions together through a Time Delay vi (Programming -> Timing palette)
You can use a flat sequence structure (Programming -> Structures palette)
You can use a State machine (

You'll want to use a State Machine if you're implementing this in Teleop.
The others can be used if this is a stand-alone task that can be independently implemented in Periodic Tasks.vi
