datafinder toolkit with LabVIEW 2013

I have a small simple VI that does not return the results I desire.

My VI will search DIAdem for a specific record name.  Then, I want to retrieve the date time called modifyTime from the File Level.  However, my simple VI gets a 305502 error.

I can retrieve all other string and I32 data, but not the date time data.

I am just learning this toolkit have hit this wall that I can't seem to get over.
