Help with Java Script w division when both numbers are 0 until user input

[Guest]

Hello I am a beginning to both Adobe and Java.  

I am trying to do the division of two fields = S5totalotherrev / S5MealequivalentRate

However, both fields are blank until the user enters data, which I discovered returns an error.  So after reading some of the others posts, I wrote the following script: (note I'm only doign the check on S5MealequivalentRate because the data isn't entered until later in the form and I didn't know how to write it to check both)

Var nRate = this.getField(“S5MealequivalentRate”).value;

If(nRate !=0){event.value = this.getField(“S5totalotherrev”).value / nRate;} else {event.value = “”;}

I'm getting a syntax error and since I basically have no clue when it comes to Java I don't know what I did wrong.  

Can someone help me with this script?

Thanks

Use the character ", not “

Use var, not Var

Use if, not If

Info: Acrobat uses Javascript, not Java

Okay I switched it, but I'm still getting an error.

You probably didn't fix all errors.

var nRate = this.getField("S5MealequivalentRate").value;

if(nRate !=0){event.value = this.getField("S5totalotherrev").value / nRate;} else {event.value = "";}

Thank you.  That worked.  This is so confusing when you don't understand it.
