@bewithjatin It seems the error is exactly what it shows: Property ‘mobile’ does not exist on type ‘ContactPage’.

You use the mobile property here:

let body = {
action:“common_register”,
mobile: this.mobile,
city: this.city,
name:this.name
};

Look that you reference this.mobile, but there is no mobile property. You also have [(ngModel)]="mobile", that expects a mobile property that isn’t in your class (although it shouldn’t give you a error, the error is the first case).

Solution:

Just create the property:

export class ContactPage {
    
    public mobile: any;

    constructor(....

You probably will receive similar errors with city and name.
