EXCEL IF-Function

Hello, I use the IF-Function and want to count the times my members came to our group meeting, this is my table, it's in German but at the C column green means the person came and red means he doesn't came to the meeting, now I want all the green columns, for now it's C and E to count together and to show in column A the result like if C2 and E2 is "Anwesend" show in A2 "2" but I can't count different like this I only did it with the column C, as you can see this worked but I couldn't figure out how to add more columns and further there will be more columns, I would be happy if you can help me!

And sorry for my English 😕

Greetings
