Overview. For sensors like the VEX Ultrasonic sensor that return a range of values, we often simply want to check if the returned value is more than, equal to, or less than some value called a threshold. For example say that we have the sensor set up and are driving around, but we need to stay at least 5 inches (127 mm) away from any obstacles.
How do I tell excel to treat a  in an excel formula as a ? :) Excel reads quotation marks as signifying text inside, but my text field requires a  to be included in it as well, so I need to somehow tell Excel that the  is part of the text field within the two s :p. Does that make sense? Mike.
To enter an array formula, press CTRL+SHIFT+ENTER. Use the COUNTIF() function to count the occurrences of a text string.
