sharing button icons for social networks

i attempted to add some html code to add a button from a social networking site that i frequent. i see the text when i do a search for my site, but it doesn’t show up on my pages/posts…

i’m using pixeled by samk

the instructions from this particular site instructed me to insert the code in a particular part of the code, but it wasn’t actually there – only something similar – which they said might happen

is there a plugin that works better that doing it manually, or can someone assist me with the code placement?

thanks in advance!

fyi, my site is http://www.kreativesouls.com
