Here is what I found that was preventing button S11 and S12 from working :
In the code where:
if (x == 10)
{client.print (content_main_top);
client.println(S10);
Serial.println(S10);
my code was in here and it had a return nested in it that should not have been and prevented any other statements below it
from being executed...my bad
}
I can now start making more buttons and rewrite the functions properly . This has been a great weekend of learning !
