i usually find this error especially when there is a typo or wrong use of a character in the code, do you mind sharing the code so i can look it up?

it means that you are trying to use forEach on something that is not an array - to know more you will need to share your code

Thank you all for your swift response, I actually was doing something wrong, but am fine now.

Thank you
once again
