XML file validation with JavaScript?

[sehuds2]

Need some help trying to figure out if this XML/Javascript seems logical. Mainly I want to make sure that the logic on the errors is right. If the ValidWhen variable fails, I want error 1. If the ValidWhen2 variable section fails, I want error2.

I was thinking there was a connection between the variable name and the msg name?

<javascript>
boolean MyTestPassed= false;
int NumberOne = 10;
int NumberTwo = 15;

if (Field1 !=null) {
if (Field1 >= NumberOne & Field1 <= NumberTwo)
{
MyTestPassed=true;
return MyTestPassed;
}

else if (Field1 = null) {
MyTestPassed = true;
return MyTestPassed;
}
else MyTestPassed = false;
}
</javascript>

<field property="Field1.entered" depends="validwhen">
<msg name="validwhen" key = "error1.fail"/>
<msg name="validwhen2" key ="error2.fail"/>
<var>
<var-name>validwhen</var-name>
<var-value>
(
(
(
*this* == 'true'
)
and
(
(fielda !=null) and
(field2 !=null)
)
)
or
(
*this* == 'false'
)
)
<var-value>
</var>
<var>
<var-name>validwhen2</var-name>
<var-value>
(
(
(
*this* == 'true'
)
and
(
(MyTestPassed = true)
)
or
(
*this* == 'false'
)
)
<var-value>
</var>
</field>
