Move Complete Rows to bottom of Worksheet

Hello All,

I have created a VBA worksheet that is populated by 2 userforms. The "add new shop order" userform populates the SOL tab and the "Look up shop order" populates the Tool_Room tab and also the SOL tab. All the data is entered using the two userforms. On the Tool_Room worksheet I would like for all the rows with a "Date Complete" entered to be moved to the bottom. For example if someone uses the "Look Up Shop Order" userform and enters a "Date Complete" and saves the information. I would like that row to be moved to the bottom of the Tool_Room worksheet only. I have attempted a few codes and managed to have the code do it manually but I would like it to happen automatically whenever someone enters a "Date Complete". I have attached a copy of my workbook, the password to unlock the sheets is (pass: abc) and the password to save the "look up shop order" is (pass: Secret). Thank you so much for your assistance I am absolutely stuck.
