Compare cells to named range and create new sheets using related named range

[drewship]

Hello all,
Please see attached example. Looking for some help to ignore sheets with the same names and create new sheets by comparing the value on the Maintenance sheet column D to the named range 'CustomerNumber' which is in column A. The code should take the corresponding value from the named range in column 'B' 'CustomerName' (add the underscore between names like Robert_Jones), compare it to the current sheets, and create any sheets that do not exist using the converted customer name as the name of the sheet before the Maintenance sheet. The code should also create a hyperlink on the Summary sheet for every customer sheet created and a link back to the Summary sheet in cell A1 of the created customer sheet. If there is a way to sort the customer sheets (or all sheets) alphabetically that would be great.

Thanks in advance!!
Andrew
