We can't "see" the code, we don't know what drivers you are using, we don't know what version of LabVIEW you are using, we don't know anything about your LabVIEW experience (looking at LabVIEW code would give us a clue). We can't suggest how to fix a LabVIEW routine when all we see is a "picture" of the Front Panel.
Maybe you should attach (as a bare minimum!) your VI ...
