innertext='{{numb}}*'
a simple heavy wildcard for example
numb variable datatype has to be of string or int (string in your case)
When you set a default value (e.g. β13β) then you also can validate the selector it by using the default value
yeah I did it same , new error came while running. Looks like selector issue is gone and while running new error is popping up
Error looks like this
