How Can You Edit Menu & make a message display a variable?

I used the turtorial on the website to make fishing in my game. The Fishing level is not displayed anywhere which is kinda dumb. So I wanted to add it either to a new page in the menu or make a fishing guy say "do you want to know your fishing level?" and then tell you what level. I really want to know the first one more but the second one will do... Can someone tell me how?

To display a variable in a message use \V[ x ] where x is the number of the variable.

To make a menu addition would require scripting in a new window, annoying and painstaking, but nicer in the long run.
