Restrict entry box( type english Characters)

 I use storyline 2

Hi there, Sofia.  I'm not sure if there is some JavaScript that you can use to notice if users are entering non-english characters, so I'll defer to the community here!

Would it be workable to give the learner some instructions about only using english characters?

Thank you crystal ,  i mentioned that they have to write their names in English through  the intial value of the entry textbox . But  it will be better if i managed to force keyboard to write english letters only because the users are youngs and sometime they dont pay attention to that.... 

Also, i encountered another problem 🙁

I inserted entry textbox and button for submition ... 

I added trigger that prevent submission if the entry textbox is blank 

I noticed that when i press "space "key ...i can submit it even if it is empty 

Hope someone can help
