I have a sheet that includes a multiselect dropdown of topic areas for users to select as many as are applicable as they fill out the form. In my dashboard, I want to have a pie chart that includes percentages of each topic area that are selected. However, the COUNTIF formula does not count anytime someone selects more than one option. I think I have to combined COUNTIF and HAS, but it has not worked for me yet.
So far, I have created a metric sheet, but need help in making the formula. The screenshot below is of my current formula (TA Tracker Range 1 is the original sheet I am pulling this from) Thank you in advance!!
