CS1003 0246 No position !

[Max238]

Hello, I might finally be able to code after all these years...
I only have three errors left to correct. One CS0246 and two CS0103
I looked at the help pages, but I still don't understand. I use "if", it's spelled correctly

.Solved. It was necessary to add "using"
