hiding <tr> in Netscape?

I want to hide certain rows of a table depending on what selection the user makes.

Here is my code that works in IE 6, but it doesn't do anything in Netscape 6.


If s == 'SP' then I want to hide some of the rows, if not then I want to show them. The rows each have a unique ID - 'OwnerPct1' etc.

Code:

---

Function swEntityType(s){

        var OwnerPct1 = document.getElementById("OwnerPct1");
        var OwnerPct2 = document.getElementById("OwnerPct2");
        var Owner2 = document.getElementById("Owner2");

        If (s == "SP") {
                var sDisplay = "none";
                Owner1Pct.style.display = sDisplay;
                Owner2Pct.style.display = sDisplay;
                Owner2.style.display = sDisplay;
                }
        Else {
                var sDisplay = "";
                Owner1Pct.style.display = sDisplay;
                Owner2Pct.style.display = sDisplay;
                Owner2.style.display = sDisplay;

        }
}

This is JavaScript right? Try lowercasing the F in Function, the I in If and the E in Else. JavaScript is case-sensitive isn't it? That may be causing a problem.
