I have lost my way on trying to create this macro, can anyone help please.

Many thanks for any help

1) I have variable number of sheets between two sheets called "" & "<", I
would like the first part of the macro to delete all sheets (if any) between
these two sheets.

2) I have a range of numbers (that can be repeated), I would like the macro
to run through the range and add a "TEMPLATE" sheet in between the two sheets
"" & "<" and rename the new sheet equal to the current number in the range,
but only if it does not already exist.

3) I would like the sheets in between the two sheets "" & "<" to be shown
in accending order

PS. I already have about 60 sheets in the workbook and the above macro could
up to another 40+, is there a limit to the number of sheets a macro can add?
