Hi the library is only supporting 2 digits behind dot.
How can I show 4 digits behind the dot i.e. 0.0001 kGal ?

Excellent work! Just 1 question – I’m trying to make a converter that will allow the user to enter a value into text box 1 and it puts the answer into text box 2 OR if they put a value into text box 2 it will put the answer into text box 1 – I can do one or the other, but if I put in the calculations for both, it seems to try to apply the formula both ways – Celsius to Fahrenheit conversions for instance.
Thank you for the time you’ve put into the great project!

It is possible to have 2 FormularCalc’s on 1 page, i have a 6 rows each with a hour * amount to create a subtotal for labout, and the i have 12 lines with QTY and amount to create a subtotal for Parts, then i also wanna calculate Labout and Parts to create a total amount due.. all works good with the labour, actually works like a dream with the checkboxes and everything, as i also wanted to have items on the invoice that were not billable but show the amount, so the script works great, just want 2 more calculations

As is it can’t, but it’s a one liner change. Next time I’m working on it I’ll see if I can add that in as a configuration parameter. If you change line 57 of ColumnCalc.js to:

[code]]czo3NDpcInNsaWtjYWxjLmFkZExpc3RlbmVyKHJvd0NvbmZpZy5pZCwgXCdibHVyXCcsIHRoaXMucHJvY2Vzc0NhbGN1bGF0aW9uLCB0aHtbJiomXX1pcyk7XCI7e1smKiZdfQ==[[/code]

That should work. You would need the same change made to line 95 of FormulaCalc.js.

Brad,

Thanks so much! It’s working well. One last question, can the script work with a onBlur event instead of the default keyUp event? I’ve tried changing it with no success. Thanks again for creating this valuable script.

If you have a reference to the calculator object, you can call object.processCalculation() on it inside of your event handler for deleting a product.

Your script is really nice. I have implemented it in an application and it works beautifully with one exception. I have a order entry form where a user selects a product and then the calculations are performed. When they want to add an additional product they click on an add row button. They add a new product and everything calculates perfectly. However, if they delete a row the calculations do not update. It’s like they are held in the cache and not updated. Specifically, I am using the FormulaCalcRows options to calculate rows and sum a total. How can I get the script to recalculate when a row is deleted? Any help would be appreciated.

Can this be used in a PDF with form fields? How would I set it up the Custom Calculation Script of the Calculate tab in the Text Field Properties?

I am attempting to get an order form set up as a PDF with form fields to calculate a formula in each item row:
Price = (Quantity – 2) * .25
The Quantity is set up as a separate text field for each item.
