Using InstallOptions_Read to Get User Input

[perfectfuture]

I'm trying to use the following to read the state of field 2 when the user clicks the next or close button. However when I print $R9 out, I don't receive the value. Eventually these will be strings I'm trying to get the value of, but does anyone have any ideas?

!insertmacro INSTALLOPTIONS_READ $R9 "one.ini" "Field 2" "State"

P.S. I've read as much documentation as I could but I realized that the InstallOptions have been depreciated and as a result I didn't find much.
