Hi @prathyoo ,
Method 1
- Make it as Bussiness Required in column setting

Method 2:
Add below java script in Form Step
Example : Note* --> make changes based on your the field name/id
$(document).ready(function(){
//Replace Next with actual id of Next button
$("#Next").click(function(){
var fileInput = document.getElementById("fileInput");
//Change fileInput with actual id of file field
// Check if a file is selected
if (fileInput.files.length === 0) {
alert("Please select a file.");
event.preventDefault(); // Prevent form submission
}
});
});
