Search Database Excel

Hi there,
I'm an amateur excel user, and not familiar with the VBA and macros. Currently, I have a task from work that I need to create a userform with one listbox, when activate, it links to a combobox option, finally a text box to fill in the description to lookup . And of course, the last one would be a command button to command for search data from a database. I have been trying with different VBA codes and still stuck for almost 2 weeks. The problem is that when I select listbox 1 as filter 1, duplicates values appear, then select one of them linked to combox 2 as filter 2 also have duplicates values. I have no idea how to solve this. Please help me to find the easiest way to nail this task.

You can find the sample I've attached to see what I mean. Simply, I need 3 filters, 1 for supply plant, 1 for shipto and one for product type and a search button to search for the rest of criteria.

Many thanks
