I need the code to show me. the number of letters I type. It's the JavaScript that I'm focusing on. For example, if I type "belch", it should show me $5. The code is attached below. Please help me of you can. https://code.sololearn.com/W69UMNd6A8U1/?ref=app

I've already gotten that. Thanks. I just put the cost variable definition and ask that into the display function and it worked perfectly. Check it out https://code.sololearn.com/W69UMNd6A8U1/?ref=app

Must it be el or the el here is just standing for a variable?
