Fixed skip pattern issue regarding 2.37 Womens Followup 18mo. Fixed code for Q2.50 Womens and 2.12 Mens for 18mo survey. Added answers of Male Sterilization and Female Sterilization to questions 3.9a women and 3.14 men. QUestion 3.10 in womens 18 mo survey was originally and mistakenly written into the code of 3.9a, it has been separated into its own question now.
