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:

slikcalc.addListener(rowConfig.id, 'blur', this.processCalculation, this);

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.

From just reading your description, it sounds like you’ll have a textbox input for the candle size, and then a select box for the scent strength. Based off of these 2 inputs, it looks like you calculate 3 outputs. This could easily be done with 3 formula calculators, where you plugin the two inputs, and put in the appropriate formula to calculate the desired output, typing that to the proper field to display it. Sorry for the generic answer, hopefully that helps out some.
