The VI looks like this (very basic and simple) but the computer crashes all the time, looks like the HiQ doesn't do a damn thing: 1. control set to, say, 10 - integer 2. control connected to HiQ script box to input "x" 3. input set to integer 4. output "y" set to integer 5. indicator connected to output 6. inside HiQ scipt box: y=x; Tha's all! It crashes all the time showing the error. Could anyone tell me what's wrong with it? See the VI attached. Thank you.
