Total calculation across merge in fields does not display until use click into one field

[Lenka0D4B]

Hi,

I am having an issue getting auto-triggered total across a few text fields that have been merged in when PDF file is opened. The total is displayed as 0 until the clicks into any field used in calculation at which point the total gets correctly displayed.

Is there a way to do this with a custom calculation script or is the trick in something else?

Cheers

Are you using document level script to calculate total when file is opened?

Try add this to your script:

this.calculateNow();
