Custom Field is not updating

[Tehmina Aslam]

I have a custom field Coins, i want it to be updated based on the value of other custom fields (all are numeric fields)

I have set up rule: I want Coins to be updated 

Complexity is 2

Effor is 3

Coins = (2+3)/2 = 0.5

The rule is showing this error.

Hey @Tehmina Aslam 

As you can see in audit log, rule is showing, that error is in syntax.

Hi @Tehmina Aslam 

First thing, in your Edit Issue Fields action you are trying to update the field two ways: with the field dropdown and with JSON.  Only one of those may be used at a time for a specific field, so remove one of them.

Next, there are errors in your math expression: it is missing the precision for the ROUND() function, and there are mismatched curly brackets for the smart values.

Kind regards,
Bill
