Thank's a lot Dan! You really help me (sometimes one image is more than 1.000 words). Now I have mores questions but the most important is if you have any idea about if it's possible to define a range (2 rings of beggining and end of crop in the front panel) to extract a range of data by date doing it using variables, and then use them in a formula node to have results. this is why I asked for a user guide or manual about variables and propertys in labview. thanks in advance, AgroADV Here is an example of how to select the text from a ring control. Does this help? Dan

I'm working on my final project. I succeed in reading a txt file from a datalogger and represent a graph ordered by time and date (hard for newby's na dI wisht to thank all the info that I found here). Now I need to make a control to select some dates as a user in the front panel, and I read some posts about it, and I don't succeed because I don't know how to work with variables (as ring or listbox in the front panel, selecting data from a string). In the labview help I didn't found interesting examples and the information is a little bit difficult to understand (agree?). Does anybody knows where I can find a specific manual or help or some examples about to work with variables, poperty nodes, etc.? i post my .vi to know your opinion if I'm doing it right, and because my english is very poor. Thanks in advance, AgroADV
