UserForm textbox data to empty cells

[RLWells]

I am completely new to using VBA and need some help. I am attaching the workbook to make it easy to understand what I'm referencing. I created a userform with 2 text boxes and 3 buttons. I need the data in the boxes to populate columns B and C starting at row 6 and ending at 48. I have seen several similar questions but when I try and use the formulas provided for answers I get errors After typing data in the 2 boxes the Ok button should input the data and close the userform. The next button should input the data and clear the userform. Any help would be appreciated!
