Hi, Liju.
In addition to Kenny's good advice, I've attached a little excerpt of code I keep around to show customers how to programmatically run another VI dynamically. It's written in LabVIEW 8.0, but I'm attaching a screenshot as well just in case you're using an earlier version.

Of course, you will only need to use code like mine if you want to select your VI dynamically -- if you know which VI it is beforehand, you can just place the subVI on the block diagram as usual.
Good luck! Let us know if you have any more problems.
