Coding comboboxes to limit to list

I am working with a project that has a series of workbooks to collect data from our various machine operators. They fill out a row of data, including a combobox for listing any problems during a particular hour. If there are multiple problems, they can click a checkbox and add an additional row. This adds a new combobox to the new row, but I can't seem to figure out how to make it a comboboxlist, type 2, which limits entries to the list in the drop-down. With these newly generated comboboxes, the user can enter anything, and we don't want that. In the existing comboboxes, I simply set the style property to 2 - comboboxlist, but I can't figure out how to apply that to the code.

This is the code I have for the new comboboxes:

PHP Code: 

    'To add combobox for problems
    Set x = ActiveSheet.OLEObjects.Add(ClassType:="Forms.ComboBox.1")
    x.Name = cmboxName1
    
    x.Height = Rows(rowOffset).Height
    x.Width = Columns("G").Width
    x.Left = Columns("G").Left
    x.Top = Rows(rowOffset).Top
    x.Object.Font.Size = 10 


Any help would be appreciated!

Is this a form?
you should use a form, and control things that way rather than creating more and more combo boxes on a sheet.
the form allows users to enter data, then it can post this data to the form
the combos can be visible or not
or limit to the list using MatchRequired property.

It's not a form, this is an inherited project, with about 20 different workbooks, one for every machine. They have been using them like this for several years, the operator enters their data every hour, then click a checkbox transfers the data to a separate workbook. Every day the workbooks are cleared, the new data is entered at the top, and the operators continue the process. It actually works pretty well, but the recent migration to 365 combined with network hiccups has brought some issues. I'm adding some checks to prevent double-posting...it will now look in the destination sheet to make sure the particular hour being submitted isn't already there, and I put in a check to make sure they aren't skipping hours, before they could enter data in any of the hourly slots at any time, now they have to go in the correct order. Some other things are in the works

One thing that has always been a problem is this combobox problem; it was never set to restrict the options. I did that for the existing ones, it's just the newly generated ones that are allowing the user to type in options not on the list. And I'm not sure how to apply this...using the code from above, I don't know how to access the style property.
