You need to explain grails, that he local variable value should be accessible in the view, by returning a map of all variables, that should be accessible in the view:

class MainController {
    def test = {

        def value = 111.10
        [value: value]
    } 
}

it should be working, maybe you are in the wrong controller method. is your gsp name seriously upper case? double check, whether action name and view name is the same.
