Description

On formcreator, some people uses dropdown or radios questions to display a list of numbers:

Then, they define condition like if value is less than X.

At first we didn't support these conditions on native forms because they only make sense when using number values, which is not mandatory (so if someone use text values, this kind of condition would be kinda useless).

But, since this is a common use on formcreator, it prevent some users from migrating as they require theses conditions to work.
To make migration easier, I've decided to allow them.
