to wind one field to another here i want to if user filles any value in annual gros income field then i want below of this field i have another field like monthly expences so i want to fill default value of this monthly field is fills by formula like annnual_income/12*.8 how to set this formula to update my this field default value while both field have same wire name like details whoose have collection wire in my collection
@rbdwt09 I would implement a listener Bot for this. Let me know if you have any difficulties 
how to implement any example of this type formulated default value set.
becouse i dont save value in collection i just want to keep payload for every fieldvalue so ihow to manage this field default value to set based on uper field like 80% of annual income field value i made collection wire to make my fields so how to integrate listner bot. for this
@rbdwt09 Unfortunately it is difficult to understand exactly what you are trying to achieve?
Can you please create a clear requirement for us. Something like this:
I have a field with a record value of x.
I would like to have a formula that does y.
I would like to use the new value for z.
etc.
Thanks
@UES.IO-Support I have two fields: Input and Output, both of type Number.
I want the Output field to automatically show Input * 2 whenever a value is entered in Input.
I tried updating the Output field using a signal, but since it’s a Number type, it’s not allowing dynamic expressions or formulas. I’ve set up a test field to demonstrate the issue — please refer to the attached video for details.
Could you please suggest how to achieve this behavior?
