# Extended condtions

 * Longtime Caldera user and now I have now come to a point where I need a certain
   function I cannot find, probably because it doesn’t exist. However, perhaps someone
   here can help me out by pointing me in the right direction.
 * One of my forms accepts a serial number, I want to verify this serial number 
   before the user can submit.
 * It’s very simple to verify the serial number. All that must be done is to sum
   the first 10 digits contained in a 12 digit number. If the output equals the 
   last 2 digit number, the serial number is valid.
 * For example:
    832126703335 > 8+3+2+1+2+6+7+0+3+3 = 35 = VALID 787537878334 > 
   7+8+7+5+3+7+8+7+8+3 ≠ 34 = INVALID
 * This is a simplified method of the one that’s actually implemented, but the question
   applies to the example just as much. Basically, with some simple math, a serial
   number can be validated.
 * Does a Caldera plugin exist that will allow me to add this functionality? If 
   not, where can I start to add it?
 * Thanks.

 * Hey Bbbenji,
 * This is an interesting use case. We don’t have a plugin or field that would do
   this specifically. If developing this or paying a professional to develop it 
   is something that you’re interested in, we have Developer documentation on the
   website as well as recommendations for our implementation partners.
