I really like your plugin, but it doesn't exactly function like I think it should. For example, when there are multiple numbers in a field (multiple choice in my case), it always takes the first number to calculate with, while most of the time the number that I want to calculate with is the last one.
I think the best solution for this would be to give a value to a field (with an extra option in field type settings without even having to define the value in the shown field.
A more simple solution would be to give importance to numbers behind a $ € or other. By looking at the code, I think you've already tried this, but it isn't working yet.
Thanks in advance,
