Hi,
I checked the video and i think i found the issue. In the button click event, a condition needs to be added to check whether row already exists. I exists update the quantity and total. otherwise create a new row. I think currently it is adding row without any check.
Pls PM me to discuss further details.
I have 3+ years of front-end devlopment using HTML, CSS, JS, jQuery, Bootstrap and AngualarJS. I am proficient programmer in asp.net and php also. I can assure you that I will provide quality work in given time period without any issues. The final code will be delivered with comments and documentation.
Looking forward to work with you,
Kasi
