Hi guys, I'm encountered a syntax problem that should be easy to solve but I still can't nail how to write.

I wanted to create a global called countrycode which should have the country code of a country (of course) and then use that global for conditional statements.

Take the following example, this is the code I'm running (I want to keep those observations where the variable countrycode is equal to the local ccode, which in this case is RWA):
Code:
global ccode "RWA"
list if countrycode==`ccode'
This is what the console prints:
. do "/var/folders/x9/1zrmd2qj5qj6dmw592sbwxq40000gn/T//SD51173.000000"

. global ccode "RWA"

. list if countrycode==`ccode'
invalid syntax
r(198);

end of do-file

r(198);
The capture of the database is below (keep only Rwanda):
Array

Thank you for your help!

Guido
