Sorting data based on time intervals

Hi Again!

After the great success of the last macro, i wondered if it was possible to run one to sort this data.

basically i want to sort data from the first sheet, based on the Plan Ar column, i want it to be split between 2 times,

07:00 - 18:59 and then 19:00 - 06:59 - and then all the values within each time frame put into new sheets.

I tried to modify the other macro but got in a right mess! And i'm not sure if due to the formatting it is impossible.

I would greatly appreciate a hand with this, even if it is deemed impossible.

Could someone also recomed me some reading to learn macro production for myself, as i have some spare time coming up in September and would like to learn.

Many Thanks,

Will
