Hi Ivanka,
you are right with the type description as an error.
I've made three things:
1 I rearranged the block diagram to meet programming style guide and beeing able toread what you have done.
2 I corrected the Set Control Value call
3 I added a Close Reference at the end. If you open a reference you need to close it otherwise you will get a memory leak.
I have attached the changed VI.
