I have a stumbling block in my code below.

If I do not assign a value to ComboBox11 (and the default value I want is 0)
then I get a type mismatch error when I start to enter a number in TextBox2.
If I do assign a value to ComboBox11 (using .ComboBox11.Value = "0") then
everything works with the notable exception that I when I use the dropdown
on the ComboBox to select one of my other choices (0, .5, 1) I can not
change the value. It remains at 0 no mater what I do.

Anyone have any thoughts on this?



Sub TotalHours1()

Dim bTest1 As Boolean
Dim bTest2 As Boolean
Dim bTest3 As Boolean
Dim dblElapsed

With UserForm1

.ComboBox11.Value = "0"

If IsNumeric(.TextBox1.Text) And _
IsNumeric(.TextBox2.Text) Then

dblElapsed = (CDbl(.TextBox2.Text) - CDbl(.TextBox1.Text) -
CDbl(.ComboBox11.Text))

.TextBox3.Value = Format(dblElapsed, "#0.00")

If .ComboBox1.Value = "" Then GoTo EnterCode
GoTo EndMacro

EnterCode:

.ComboBox1.Value = "01"

Else

'MsgBox "There is an invalid time"

End If

GoTo EndMacro

ClearBox:

UserForm1.TextBox1.Value = Format("", "")
UserForm1.TextBox2.Value = Format("", "")
UserForm1.TextBox3.Value = Format("", "")

EndMacro:

End With

End Sub
