Need help finding total time of a tasks listed by comma separated values in a single cell

Hello, this is my first post in the forum, thank you in advance for any help.

I am slowly but surely building a spreadsheet to analyze different elements of a training schedule. After looking at several posts I am having trouble finding a function or macro that will allow me to add up the time given to a particular training task. I have attached a sample spreadsheet to help understand what I am trying to do. I have two sets of data that are similar, but have different qualities.

I found a macro that places multiple items (CTTL and Core Tasks) in columns A and E into a drop down list as comma separated values. Within this list you can select more than one item or select an item a second time to remove it from the cell.

Columns B and F count the number of CSV items selected in the drop down box for A and E

Columns C and G are the total amount of time in hours given to a particular task.

Columns D and H are the result of the hours divided by the number of items in B and F. The result is how I break down each task in to a fraction of an hour. In cell A2 there are two tasks that I am dividing 1 hour (C2) equally between each of them to equal .5 hours (D2).

I want to add up total of time per task listed in columns A and E next to their task code in columns K and M. These totals will be used in a pie chart and provide a way of tracking each training task down to the minute over the entire course.

Pl see attached file.

Wow, that works great. There is no way I could have figured that out on my own.
