Formulas Based On Results From Dropdown Menu?

I am building a sheet that facilitates managers at our company decipher information that is given to them on a daily workbook I created.

I want to have a drop down menu in Col J, that refers to the major questions they will ask.

Time started (Before)
Time Finished (After)
Number of Cards (More than)
Stops Per hour (more than)
Amount of Time Taken (More Than)

I have set up in Col (K) a secondary drop-down list which based on the question selected in (J) will offer options for the answer E.G Time questions will make (K) refer to options based on time and selections based on amounts will offer numbers as an answer.

The elements in brackets are the parts of the formula that create the search option. E.G If select 'Time Started' it will search for all records that started before the time selected in the next col (K)

Right if that makes sense.. I have completed this. so I have the following: A question drop down list in (J), and an answer drop down in (K) which is dependant on the type of question asked. (I have attached an example)

I want to now have a totals box after the question where it displays a total amount of cols that are true to the details in the question.

After that (if possible) I will want to use conditional formatting to highlight the ones that reflect to the question.

Realistically if possible i wouldnt mind creating a question box, a box that allows them to select 'more than', 'exact' or 'less than' and then the specific value. Basically a conditional formatting box for dummies within the worksheet. Attached is a demonstration.
