Strange error with Selection object and Userform - vba

Question

Getting a strange error with this code. This excerpt is the beginning of the main code. First it opens a form that takes 3 inputs. The inputs aren't being used right now so it's not the issue.
Public triangle As Range
Public Height, Width, i As Integer
Sub asdf()
Set triangle = Selection
WeightsUserForm.Show
Height = triangle.Rows.Count
Width = triangle.Columns.Count
Debug.Print Height
Debug.Print Width
This gives me 12 as Height and 12 as Width, which is correct based on what I've selected.
Now here is the sub that runs when you press OK on the user form:
Private Sub OKButton_Click()
Set triangle = Selection
Height = triangle.Rows.Count
Width = triangle.Columns.Count
Debug.Print Height
Debug.Print Width
This gives me Height as 28.5 and Width as 99. I have no clue where this comes from. I even checked all the objects on my userform as if maybe it was interpreting that as my selection (which is clearly wrong since those objects wouldn't have a rows property).
Ideally I would like to save my initial selection as a "public variable" if that is a real thing.
Any help is appreciated.
EDIT: Further update. I have set the variable triangle manually now ie
triangle = Range("B3","M14")
This STILL gives me the same strange dimensions. Now I'm really stumped.
2xEDIT: When I don't use the variables Height and Width and just refer directly to triangle.Rows.Count and triangle.Columns.Count it gives me correct answers. So I can run my program properly now. I would still love to know why using a variable was wrong though.
So you're saying that the line
Public Height,Width,i As Integer
is only declaring i as an integer and not specifying a type for height and width? If so that would be my problem.
I redid it declaring both Height and Width properly as integers but it still bugged out the same way. However using private variables W and H defined the same way it works. shrug

Answer 1

Reading between the lines, I think your issue is that Debug.Print Height and Debug.Print Width is printing the size of your form.
This will happen if your declarations are in a Module rather than the Form class, because Height and Width are keywords applicable to the form, so the local versions are used in preference.
To solve, you should do all of these things (not all of this is absolutely necassary, but is all good practice):
Use Option Explicit in all your modules
Don't use Keywords for variable names
Scope your variables, in order of preference, to Procedure, then local Module, then public Module, and only when there is good reason
Prefix your remote module calls with the module name, eg Module1.Height
BTW, using Dim Height, Width, i as integer declares declares Height and Width as the default type which is Variant.
