*After the colon you see the parameter repeated with the addition of a pipe after the word inside the {{{}}} and a pipe on the outside like so:<font color="red"><nowiki>{{{parameter|}}}|</nowiki></font color>. We will not take the time to explain what all this code means but if you are interested see the footnote<ref>The coding looks complicated but it is really not. First this is an “if” statement. In essence, it says “if” you have A do B or if you do not, do C.
