okay, so i found a VI that helps to communicate with serial DTE device (power meter) that i am using. Now i can send commands, like 
OWER? to get the last measured value off of the meter on to the output display of the VI.
I have been working on this VI for a while now, and want to collect data. So i created a for loop in a new VI and used the serial r/w VI discussed previously as a sub VI, with appropriate inputs. The output is a string. Even though it gives a numerical response but as a string. So i tried to BUILD an array inside the for loop and tried to collect all data. then using I/O functions i tired to output but that doesnt work. If anyone has experienced similar problem before, can u please help me out here with some stuff i should be doing . thanks
