Hello @DhruvNalakurthi ...
Are you typing in the characters into that text box? Or, are you copying/pasting the characters into the textbox? I ask, because if you are typing the characters in, the final character "l" can look like either of the following:
- upper case letter "i" as in "Iguana"
- lower case letter "L" as in "lizzard"
Have you tried either of those?
