Description

Im try to apply regex on input field for validating a user inputs; However, I get this error:

inputmask.js:1055 Uncaught Inputmask: There is probably an error in your mask definition or in the code. Create an issue on github with an example of the mask you are using. (?!^[-])(?!.?[-]{2,})(?!^[^-][-])(?![^-]?-[^-]-[^-]*?)(?![-][^-]$)[а-яА-ЯёЁ-]{0,99}

I will be appreciated, if you'd help with this problem as soon as possible. =)
