    If Statment Help

    I have a JavaScript function (listed below), it works fine but I cant get it do one more thing. The problem is if any of the fields are empty or below zero the sum will be -1.11 or some other wrong number. I want it to only calculate if all fields (M3, M4, and M6) have a number above zero. Can someone please help? Thanks.

    This is the code:

    this.rawValue = (Number(M3.rawValue) - Number(M4.rawValue) - Number(M6.rawValue)) - 1.11

    Well the best thing I can think of is three local variables, and test them individually.
    Code:
    var M3 = Number(M3.rawValue), M4 = Number(M4.rawValue), M6 = Number(M6.rawValue);
    if (M3 <= 0 || M4 <= 0 || M6 <= 0) {
        // Deal with the error
    }
    else {
        this.rawValue = M3 - M4 - M6 -1.11;
    }

    I tried the code below but it done not work. Dose it look like i put it in there right?


    <calculate override="error">
    <script contentType="application/x-javascript">var M3 = Number(M3.rawValue), M4 = Number(M4.rawValue), M6 = Number(M6.rawValue);
    if (M3 &lt;= 0 || M4 &lt;= 0 || M6 &lt;= 0) {
    }
    else {
    this.rawValue = M3 - M4 - M6 -1.11;
    }</script>
    </calculate>

    It must <=, not &lt;=. They display the same, but are totally different.

    And if you aren't going to treat the error
    Code:
    if (M3 > 0 && M4 > 0 && M6 > 0) {this.rawValue = M3 - M4 - M6 -1.11;
    }
    is more logical.
