Help looping until a certain cell value

Ok, this is going to be easy for anyone comfortable with vba to answer. I however am a beginner. My goal is simple, but I wanted to do it through code, just to challenge myself. What I want to do is go down the row and if column E is a certain value, highlight A-E in that row to be a certain color. So if E3 is the number 2, I want A2:E2 to be highlighted orange. Likewise if E7 is the number 4 I want A7:E7 to be highlight blue. Make sense? Alright here's the code I wrote to attempt to make it work:

Sub priority()
'
' priority Macro
'

'
Dim cellnumber As Integer
    For cellnumber = 5 To 144

        Range("E & cellnumber").Select
        If Selection.Value = 1 Then
        Range("A& cellnumber:E& cellnumber").Select
            With Selection.Interior
            .Pattern = xlSolid
            .PatternColorIndex = xlAutomatic
            .Color = 192
            .TintAndShade = 0
            .PatternTintAndShade = 0
            End With
        ElseIf Selection.Value = 2 Then
        Range("A& cellnumber:E& cellnumber").Select
            With Selection.Interior
            .Pattern = xlSolid
            .PatternColorIndex = xlAutomatic
            .Color = 49407
            .TintAndShade = 0
            .PatternTintAndShade = 0
            End With
        
        ElseIf Selection.Value = 3 Then
        Range("A& cellnumber:E& cellnumber").Select
            With Selection.Interior
            .Pattern = xlSolid
            .PatternColorIndex = xlAutomatic
            .Color = 5296274
            .TintAndShade = 0
            .PatternTintAndShade = 0
            End With
         ElseIf Selection.Value = 4 Then
        Range("A& cellnumber:E& cellnumber").Select
            With Selection.Interior
            .Pattern = xlSolid
            .PatternColorIndex = xlAutomatic
            .Color = 15773696
            .TintAndShade = 0
            .PatternTintAndShade = 0
            End With
                
        End If
        
    Next
    
End Sub

I know where I'm going wrong. It's the "Range("A& cellnumber:E& cellnumber").Select" part. The problem is that I don't know how to say, if x = 7 select E7. I know there must be a simple way to do it. I remember from reading something that the & operator joined things, but clearly my guess at the syntax here isn't correct. Thanks for taking your time to help.
