I am using arduino uno for a project.I need to record when my sensor gives a high value but i need it to read only falls in pulses.The program is giving  error as
Arduino: 1.6.3 (Windows 8.1), Board: "Arduino Uno"

Sense.ino: In function 'void setup()':

Sense.ino:14:38: error: 'blipCount' was not declared in this scope

Error compiling

please tell me what is the problem with the function.

tested the code on both 1.72 and 2.19

user5063: You have a typo:
PCintPort::attachInterrupt(SensorPin,blipCount,FALLING);

Should be:
PCintPort::attachInterrupt(SensorPin,blipcount,FALLING);
                                         ^

Note the lower-case "c".
