When using the number box in the form, there is no thousand separator in the number displayed. This makes it hard to see the value, especially for large amount like hundred thousands and millions. However, if use text box, this doesn't allow the math control action to be used for that particular field. Will be good to have comma(s) in the number displayed so that it's clearer.
Thank you for this idea. We understand the desire for this feature and will consider it as a part of a future release.
