Greetings! I created a userform with two combo boxes (CategoryComboBox and ItemComboBox). Each category in the CategoryComboBox has specific Items that should be populated and selected in the ItemComboBox. Sheet1 is where I enable the userform to input data and Sheet3 is where I make my Category List and Item List. My Item List for each category is not yet complete. Please help me with the codes on this. Will I be able to add Items List as I go and not affect the way the user form works? Thanks.
