Excel Marco for assigning stars for p values, delete diagonal pattern of cells

***set e to bonferroni, if no bonferroni, set e to 1

Sub bstars()
   
Dim c As Range, e As Long
e = 10
For Each c In Selection
    If IsNumeric(c) And c < 0.001 / e Then c = "$^{***}$"
    If IsNumeric(c) And c < 0.01 / e Then c = "$^{**}$"
    If IsNumeric(c) And c < 0.05 / e Then c = "$^{*}$"
    If IsNumeric(c) And c < 0.1 / e Then c = "$^{#}$"
    If IsNumeric(c) And c < 0.01 Then c = "$^{#3}$"
    If IsNumeric(c) And c < 0.05 Then c = "$^{#2}$"
    If IsNumeric(c) And c < 0.1 Then c = "$^{#1}$"
    If IsNumeric(c) And c >= 0.1 Then c.ClearContents
Next
