IS this Possible

I am Creating a Form to Track The Number Of Spaces in a Parking Lot. The End User would input whats ever was counted in the way of space then input that information in a TextBox. I have written the following code to handle the math portion of the program, the only problem is that I would have to write this code 265 times. the question is can this be done as a range of textboxes.

Private Sub TextBox49_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim Total As Long
Total = Val(TextBox1.Value) - Val(TextBox25.Value)
TextBox49.Value = Total
End Sub
Private Sub TextBox50_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim Total As Long
Total = Val(TextBox2.Value) - Val(TextBox26.Value)
TextBox50.Value = Total
End Sub
Private Sub TextBox51_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim Total As Long
Total = Val(TextBox3.Value) - Val(TextBox27.Value)
TextBox51.Value = Total
End Sub
Private Sub TextBox52_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim Total As Long
Total = Val(TextBox4.Value) - Val(TextBox28.Value)
TextBox52.Value = Total
End Sub
Private Sub TextBox53_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim Total As Long
Total = Val(TextBox5.Value) - Val(TextBox29.Value)
TextBox53.Value = Total
End Sub
Private Sub TextBox54_Exit(ByVal Cancel As MSForms.ReturnBoolean)
Dim Total As Long
Total = Val(TextBox6.Value) - Val(TextBox30.Value)
TextBox54.Value = Total
End Sub

I am Sending the entire Program any and all help would be greatly appreciated. Thank YouHourly Counts.xlsm

thank you so much

I am sorry for the delay, That is what is being used right now but the end-users for whatever reason find it hard to use that form require the current date to be input so that the form unlocks If There is a way to lock the date cell or cells after input might help. another problem with that excel base form is when looking up a previous date it is asking for the date to re-enter i am enclosing a copy of the sheet so u can see what I am talking about, Space Counts.xlsm

Once Again Sorry for the delay Response, But The Math portion is just part of the forms subtracting what the end user puts into the Textbox. The Computer generates a number based on the capacity of the Lot. What ever The End User Puts in the Textbox is subtracted from what the Computer is is showing at the time of the count.
