Execute command troubles

execute @e[type=armor_stand,name:"Luis Fonsi"] ~ ~ ~ /particle witchMagic ~ ~ ~ 0 0 0 1 1

I'm trying to make a meme armor stand and add particle effects but I can't seem to get the execute command working because it doesn't see the name properly cause it has 2 words. I know I'm doing something wrong but no idea what

I'm playing in 1.12 on a server. If that helps Entity '@e[type=armor_stand,name:"Luis' cannot be found Error Message ^

I managed to accomplish the same thing just by using this command:

execute @e[type=armor_stand,c=1] ~ ~ ~ /particle witchMagic ~ ~2 ~ 0 0 0 0 50       

Basically it looks for the closest armor stand which is the one i want to edit. Its not really helpful if you want to do it by name but its an easy solution.
