can't put writing in signature

[sunshine]

Hello, I am new here and would like to add some writing like my current weight/goal weight etc to my signature to show with every post I do. I am adding this to the sig box but it won't show up. I did tick the box that says include sig, so who knows. Help would be much appreciated!!
