Calculation question - new to this

You may want to start looking at the tutorials, articles, and eSeminars on demand to develop some basic sense about Acrobat JavaScirpt and see links to additional documentation.

I did that, thanks! Apparently I was just reading into the calculations more than I should... I thought, like Excel, you had to know the exact position of the data you were looking to calculate, as oppossed to just using the names of the data field themselves in the calculation, so I got everything to calculate right.

However. I am now getting errors in the three fields that have the calculations. They work fine, but three pop up boxes show up, one after another, telling me that "the value entered does not match the format field [current LTV] with "current LTV" being one of the three fields that I put the calculations in.

Upon opening the form, all three fields have "0.0%" in them, which is what it should say as there isn't any data in the other fields, however, the people that are going to be using this field are going to get very confused when they get an error and instead of just clicking "okay" they will not even use the form.

I'm sure there is an easy workaround, yes?

You should post the code or the file. You probably made a mistake somewhere.

I am a complete novice. I have read numerous articles to try to get the answer to my query and feel more confused than when I started... I feel overwhelmed by Java Script!

I am trying to create a calculation in an Acrobat 9.0 form which works out the installment payment dates based on an inception date, the number of agreed payments and the overall time period. i.e.
DueDate1 = "if Payments is more than 0, then add Calc1 [which is number of days between installments] to Inception else leave this field blank".
DueDate2 = if Payments is more than 1, then add Calc1 to DueDate1 else leave this field blank".
Etc. up to DueDate11

Based on one article I saw, I put in the following in my DueDate1 field:

var nPayments = this.getField("payments").value;
if( nPayments > 0)
event.value = nCalc1 + nInception;
else
event.value = 0;

Absolutely nothing happens.

Payments = the number of installments that will be paid and is formatted as a number
Months = how long the Installment agreement will last
Calc1 = is the result of Payments / Months * 30 to give me how much time to add to each installment date and is formatted as a number
Inception = the start date of the Installment plan, the date the deposit is paid and is formatted as a date.
DueDate1 = where I want to calculation to happen and is formatted as a date

Because there is a date involved and I'm adding a number to it to get a new date, do I need to change the date to milliseconds?

Help!

Maybe you should post you entire code. It's possible there's an error somewhere else.
Also, where is this script placed?

I would put curly brackets around the if-else statements, like so:

To answer your last question: What does the number represent? But yes, the best way is to convert it to milliseconds.

Edit: Also, you should have started a new thread instead of piggy-backing this one...

I'm really showing my 'green-ness'. I too thoguht that would be most appropriate but I couldn't see where to start a new thread. Can you help with that to start me off on the right track?
