Hello,

It is working on my instance.

Please share screenshots from your script. Make sure onchange field is the multi line text variable.

If my answer helped you in any way please mark it as correct or helpful.

HI @Akki8219 

Try to this code

function onSubmit() {
	var maxLength = 290; // Add desired max length here
	var varName = 'full_description'; // Add variable name here
	var multi = g_form.getValue(varName);
	var len = multi.length;
	if(len > maxLength){
		var str = multi.slice(0, maxLength);
		g_form.setValue(varName, str);
		g_form.showFieldMsg(varName, 'Max length of ' + maxLength.toString() + ' exceeded for this field.', 'error');
                return false;
	}
}

Please mark reply as Helpful/Correct, if applicable. Thanks!

Hi @Akki8219 ,

For single line text and single line long text field the limit can be set using attriutes but for multiline text you need to use the onchange client scipt like below:

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '') {
		return;
	}
	
	var maxLength = 250; // Add desired max length here
	var varName = 'max_length'; // Add variable name here
	var multi = g_form.getValue(varName);
	var len = multi.length;
	if(len > maxLength){
		var str = multi.slice(0, maxLength);
		g_form.setValue(varName, str);
		g_form.showFieldMsg(varName, 'Max length of ' + maxLength.toString() + ' exceeded for this field.', 'error');
	}
}
