I am searching for a function that only allows user to enter number,”$” and “.”

You can deploy the RegEx plug-in from Forum and write a regex to do your validation.

Hi Parisa,

Hope you are doing well! A better way to handle a dollar amount in the process would be to store the value in a Number (Decimal) type and use the Number Decimal form component to get the user input. The runtime form will do the validation for you. You can label the component as "Salary ($)" to make it intuitive for the user.

Please let me know if I misunderstood your requirement.

Thanks!

The expression

cleanwith("a123,.ddd7$", "$.1234567890")

would do the job. But I think using a simple decimal field as Abhishek suggested is a far better solution.

the field is number(Decimal) but they requested to be able to enter $ and . so i have to make it a text field
