Hi @decenababylyn20, and welcome to the forum.

I think your question is lacking some information that would make it possible for people to help you. Some code snippets or a clone link would be useful.
I’d recommend reading How to ask a good question and How to access a drop down list from an ItemTemplate form - #2, and adding all the missing details to your post.
