Generating new variable - Qualtrics export

[Chloe Keel]

I am generating a new variable based on existing variables in my dataset which were exported from Qualtrics. Using the following code:

gen X = .
replace X = 1 if Y == 1

The result is showing 0 changes made however there should be 64 changes. I've never come across this problem before, I wonder if it has something to do with the type of variable. Y (exported from Qualtrics) is double and X (that I generated) is a float.

replace X = 1 if Y== 1
(0 real changes made)

It only seems to be this one variable, all new variables have work. Anyone come across this before?

I have solved this problem.

Gen X=Y Then Replace X=. If Y! =1

You can abbreviate those two statements into:

gen x = y if y != 1
