Capturing the submatches after the second instance of a string variable - excel

Question

How would one capture two numeric submatches after the second instance of a string/number?
I have a # that changes from .txt file to .txt file. It is captured in a variable called "Total" which I declared as a string. The string contains numbers, in the format of 123, 456,789.23 or 123, 456.01. This number appears about 3 times within the .txt file, and I have written a RegEx pattern that is able to capture the first instance of this number and its submatches.
regex.Pattern = Total & "\s*([\d+\.\d*])\s*([\d+\.\d*])\s*"
The .txt file portion I am trying to capture may appear as
123,456,789.38
2.180
251.517
OR
123,456,789.38 2.180 251.517
I want to capture 2.180 and 251.517.
The first instance includes the words "Number of: " in front of it, and I tried to make the pattern avert from the ":" before it by writing:
regex.Pattern = "[^:\s]" & Total & "\s*([\d+\.\d*])\s*([\d+\.\d*])\s*"
It still picks up this first instance and the numbers after that first instance. The second instance does not have any defining words before it, just a blank line such as the one below:
123,456,789.38
2.180
251.517
Additional information:
Dim regex As Object: Set regex = CreateObject("vbscript.regexp")
regex.Pattern = Total & "\s*([\d+\.\d*])\s*([\d+\.\d*])\s*"
Dim MCS As Object
Set MCS = regex.Execute(myText)
Dim Total As String: Total = MCS(0).submatches(0)
Dim submatch1 As String: submatch1 = MCS(0).Submatches(1)
Dim submatch2 As String: submatch2 = MCS(0).Submatches(2)
where mytext is the contents of the .txt file entirely as a string.
There are also words and numbers between the different instances of the variable "Total", such as
Number of: 123,456,789.38
Text Here Text Here
Number Here
123,456,789.38
2.180
251.517
I am also not sure how much/many text/numbers there will be between the first two instances of 123,456,789.38, so I am trying to think of how to work this to be flexible.
When I mention second instance, I mean that the number 123,456,789.38 (which is the variable named "Total") appears three times in the document. I want to capture the two submatches that appear after that number. However, since there are three times it appears, I want to capture the two submatches that appear after the second time that 123,456,789.38 pops up.

Output:
submatch1 = 2.180
submatch2 = 251.517
Currently, it is capturing
submatch1 = 97
submatch2 = 5
with the pattern:
regex.Pattern = Replace(Total, ".", "\.") & "\s*([.\d]+)\s*([.\d]+)"

You can use
regex.Pattern = "^(?:[\s\S]*?" & Replace(Total, ".", "\.") & "){2}\D+([.\d]+)\s*([.\d]+)"
Here is the regex demo where you can see that
As expected.
Details
^ - start of string
(?:[\s\S]*?123,456\.78){2} - two occurrences of any 0+ chars as few as possible and then 123,456.78 string
\D+ - 1 or more non-digit chars
([.\d]+) - Group 1: one or more dots or digits
\s* - 0+ whitespaces
([.\d]+) - Group 2: one or more dots or digits.
