Why is there a run time error and how do I fix it? Could not get the list property invalid

[born2dive00]

hello every one when I open up the workbook and try to use the dropdown list in Column3 i get a MVB error message

Run time Error
Could not get the list property.

when I debug it goes to this line of code.

Controls("TextBox" & i).Text = Me.ComboBox1.List(sc, i - 1)

Now it was working when I had only 18 text boxes, but I had to add 200 more and then I got this.

What did I do wrong and how do I fix it.

Please let me know, and thank you all

Thank you all On my parts Data tab I didnt have enough columns, I stopped at 200 but had 210 text boxes, If you add or subtract the additional columns, the number of text boxes in the vba must match the number of columns.
