Hi Cindy, if I understand your situation correctly, then GetFieldValue would be returning a number and "replace" is not a method for a number. I would suggest something like the following so that it can be more easily stepped through in the browser Developer Tools.

var fieldnumber = GetFieldValue("My field name");

var fieldtxt = fieldnumber.toString();

var updatedtext = fieldtxt.replace(".",",");

It is a curious use case - if this is due to locale that you would want to do this, there could be other approaches.

Hi

That's exactly it.

We're using the local French and when some of our users write "0.531" it becomes "531" on submit ! It's a big problem. And until the problem is resolved, I'm looking for something to correct it.

Thanks for your answer, i'm trying it.

The system should take care of this automatically for you. The user just needs to be sure to use the "French" locale. There are many (maybe 20+) "French" options. Are they using one of these? Which ones? I have seen strange behavior with some locales that doesn't happen with other locales. Maybe have them try the plain "French" option instead of one of the other options. It looks like this

When you pick the locale, all the number formatting should adjust to be "normal" for that locale. If they always use comma, then comma will work. If they always use dots, then dots will work. This is nice because you don't have to code for it yourself.

this is the answer.
