ComboBox display

Good morning,

I have a quick question: I have a Combobox That I only want to display cell A2 from Sheet "PRJINFO", and I have the RowSource as PRJINFO!A2. Although it work okay, every time I open the form, the combobox is empty, and I need to use the drop down function and select the info. I want the info to display in the combobox without the need to use the drop down list and select the info?
Any help will be appreciated
