Hi again,
I got this window after validating my application. All error is when I use Float (wrtie value to float). As you can see in screen shot, my data type is real, adress is float. Don't know where I miss something, any idea?

thanks

Just guessing here, but the errors are "warning" level nothing fatal I can see. The system is unsure that your F data file will format properly into the real format. If the app will run I'd run it to see what the results look like. Kinduof like the classic PB32 warning that objects overlap when in fact it is the "imaginary" edges that overlap not the viewable ones.

Yes the application is running, I don't understand why I got this warning.
