you want to use your input button in place of link , then you can use id of the input button and use .click handler. Use HTML instance of this and Script $("#btnNext").click(function () { // Event of link-click "necxt step" if (current_step == steps.length - 2) { // checking - will it the next step is last $(this).hide(); // i hide the link "next step" $("form input[type=submit]").show(); // show thge button "OK" } $("a.back").show(); // show the link "Back" current_step++; // increase the counter of the current slide changeStep(current_step); // change a step }); do same as it is for another button

The error message suggest that you are trying to process Unicode text with a program that only handles ASCII. It would help if you remove all the code not relevant to the problem, and also indicate exactly where the failure occurs. Also, Python questions are more likely to get an answer when posted at [Quick Answers](https://www.codeproject.com/Questions/ask.aspx).
