Input text into html input box using vba

I am trying to input a value into a from on an internet explorer page using VBA. I have seen similar posts but can't seem to pinpoint my problem. I am somewhat fluent with VBA but HTML is new to me. The ID attributes change on the webpage I am accessing every time you load the page. Here is a shot of the HTML element I am trying to access:

<input type="text" size="20" style="text-align: right; width: 261px;" autocomplete="off"    id="ext-comp-1067" name="user_numbers.1.number_1" class="x-form-text x-form-field x-form- num-field" title="">

The code I am currently using is here:

    Sub OpenWebPage()

    Dim ObjCollection As Object
   Dim i As Long
Dim objElement As Object
Dim doc As Object
Dim form As Object



    Dim ie As Object
    Set ie = CreateObject("INTERNETEXPLORER.APPLICATION")
    ie.Navigate "http://11.182.123.21/#!/view/dashboards/dashboard-1"
    ie.Visible = True
    While ie.Busy
        DoEvents
   Wend


    Application.Wait Now + TimeValue("00:00:10")

 Set ObjCollection = ie.Document.getElementsByName("user_numbers.1.number_1").Value = "123"

End sub

The name "user_number.1.number_1" I think is the only element in the html that I can use to find this input box, the ID changes every time you open the webpage. How do I got about entering a value in this field?

Thank you!
