Hello,

It's really hard to understand your problem based on information your provided but I would try to answer which steps you need to take care,

- configure Amount Type = Python Code in your salary rule, code should be, result = inputs.yourcode.amount

- 'yourcode' should be configured in field Code in the list of Inputs on the same salary rule

- add this salary rule in your salary structure

- once you create any payslip and choose employee, you will see that the Other Inputs list on payslip is auto populated and you can enter Amount.

Regards
