Help with a variable script

I've abandoned the variable approach and am now working with:

---- form1.BodyPage1.Load::validate - (JavaScript, client) ----------------------------------------

if (Contacts.rawValue > "90")
{
this.rawValue = "+" + (Contacts.rawValue - 90);
}

if (Contacts.rawValue < "90")
{
this.rawValue = "-" + (90 - Contacts.rawValue);
}

endif

This works except I can't get the ( + ) sign to display

You've got a few issues here.
- You've chosen some odd events in which to place the scripts. It seems that this should be a calculation script.
- Did you remove the "enter" event before adding the "validate" event?
- In the second post, at the end of the script. There is no "endif" keyword in JavaScript
- The comparison in the second post is lexical, meaning that Acrobat is comparing the numerical values of the individual characters against one another.
- The comparison should also be an if/else structure. The way you have it misses the case when the number of contacts is 90.
- Also in the second post, JavaScript evaluates the type of operation from left to right. Logically the mixed number/string statement should work out, but still, it's better to keep this bits explicit.
- try adding a ".toString()" to the numerical calculation
For example: (90 - Contacts.rawValue).toString();
- Validate events can be used for non-standard purposes, but the forms engine still expects this event to evaluate to true/false.
- The validate event is called when the value of a field is changed. Usually this event is used to validate user input. How is it getting called here?
