I don’t want to add such feature, because over complicates the ui which is already not super simple and even worse the code.

But what you can do is to add 3 fields let’s say:
A: cost
B: amount
C: total

and with a simple JS you can pre-file C with A*B (or whatever you want), add the JS in the included javascripts using a simple WP hook called: wp_register_script and wp_enqueue_script.

As said: your rules, your power!

WP used? Settings used? Please read the FAQ and provide enough information.

But why you do not use instead the code:

global $allowedtags;

// add tag to allowed tags list
allowedtags["p"] = array();
allowedtags["br"] = array();

Please use Cimy Swift SMTP if you are having issue with your emails. Cimy User Extra Fields uses the WP default email system so nothing I can fix there.

You can email me, my email is everywhere, included the donation link which would be nice to have in mind 😉

Not a supported feature.

Please try v2.3.6 should work.
