      Please use code tags when posting code.

      You need to give us the full error text along with which line of code the error is on.

              not sure what is ambigous about this warning. it tells you that you pass an array where you should pass a string.

              reason being, you declare Skills to be an input array, so the foreach() loop's $value will be an array (and not a string like the others) for the skills key.

              the second error is caused by the first error. just fix that one and it should go away.
