How would you check the data type of a typed entry into a combobox?

I have a user form where there is a ComboBox that is meant for a number to be input, specifically the number of units desired.

I am currently coding the error prompts if a necessary ComboBox is empty, and I want to add a check to ensure that the value in the Order Quantity ComboBox is an integer or numerical value.

How would I go about achieving this?

If anyone happens across this thread here is how you do it:

ElseIf Not IsNumeric(Me.CaseQty.Value) Then
        CaseQty.Value = ""
        CaseQty.SetFocus
        msgValue = MsgBox("Please enter a number for the Cases.", vbOKOnly + vbInformation, "Missing Information")
