Excel 2007 : I need advice for a solution to a code problem

Hi, new to the board. I need help figuring out how to put a check mark in an excel cell. I have done this in the past with a web site I found but stupidly did not save my work. I was able to select the cell with one click and a tick appeared without a box, another click in the same spot and it went away. When I did this in the past I had to somehow cut and paste some "code" into the excel sheet, I do not have any clue how to even begin to do that again. I have attached a copy of the form I made in the past but cannot do again now.
