Hi i have a textbox on my userform which adds up the numerical values entered into 24 textboxs on a userform page

The code i use ensures that it does not add up the values if any textbox is empty or not numeric

as the textboxs on the userform do not need to be filled in a specific order i have had to add this code to every textbox, which has resulted in alot of code. Is there any other way i can go about this? As im having issues with my userform i believe due to too much code

If (Me.TextBox12.Value = "" Or Me.TextBox13.Value = "" Or Me.TextBox22.Value = "" Or Me.TextBox23.Value = "" Or Me.TextBox24.Value = "" Or Me.TextBox25.Value = "" Or Me.TextBox26.Value = "" Or Me.TextBox27.Value = "" Or Me.TextBox28.Value = "" Or Me.TextBox29.Value = "" Or Me.TextBox30.Value = "" Or Me.TextBox31.Value = "" Or Me.TextBox32.Value = "" Or Me.TextBox33.Value = "" Or Me.TextBox34.Value = "" Or Me.TextBox35.Value = "" Or Me.TextBox36.Value = "" Or Me.TextBox37.Value = "" Or Me.TextBox38.Value = "" Or Me.TextBox39.Value = "" Or Me.TextBox40.Value = "" Or Me.TextBox41.Value = "" Or Me.TextBox42.Value = "" Or Me.TextBox43.Value = "" Or Me.TextBox44.Value = "") Then
