As you can see from the last few lines of code the listbox is created from the sheetnames from 7 onwards (the 1st 6 sheets have a different naming convention and arent ones I wish to include in my listbox)
Now currently all sheets are included in the listbox but I am not interested in those sheets that exist in the past, only the sheets that are this months and future months.....how would I go about changing this?
