Trouble with invoke node

Hello,
I am having difficulties with one of my Invoke nodes in teh attached file. I am not attaching the vi that it calls on, because I do not think it is needed to solve the problem. I think teh issue lies in Data Type Descriptor. I do not know what kind of input to give it. The data is a string.

I would appreciate any input.

Thank-you!

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.
