I am trying to do the following for a test purpose so I am a learning mathematica

TestFun[] := Module[{a, tb, n},
    tb = Table[0.0, {4}];
    n := 1;
    a := Random[];
    While[n < 5,
        If[ a > .5,
          (tb[[n]] = a;
            n++;), Continue[]
          ]
        ]
      tb
    ]

The output that I get is

{0.871577 Null, 0.512558 Null, 0.00441806 Null, 0.520545 Null}

Why am I doing wrong here and what is the correct way to do the above thing using If and While loop?

thanks
