thanks alot both of you - the reason for displaying everything is that theyre going to be user input ie not constant. the vi posted (as an image not the attached file) by crelf is exactly the lines along which i was thinking. within the for loop that is shown there will be some form of data acquisition that will take values from the row of the listbox currently selected. however if I set the listbox to take in the loop number so as to highlight a row, then I dont know if I can also take the info in that row and pass it to the daq inside that loop. my overall aim is to set up a vi where user types in the length of 5 time intervals, the frequency of data reading (ie every 30 seconds) in each interval, the sample period (ie for 2 seconds every time) in each interval. i really am extremely new to labview and am under some pressure to produce - a bit lost at the moment! thanks for all the help, really appreciated andrew

hi im trying to set up data acquisition inside a loop that feeds it info like sample period and frequency. So for example you have three time intervals, each with their own sample period and frequency. I am very new to Labview but am thinking this may be possible using a multicolumn listbox with a row for each time interval. how do you reference to cetain elements of a listbox, or is this not the way i should be doing it? thanks very much, andrew
