As you can see in the picture, my total quota (bottom one) doesn't work. Could anyone help why this might be the case?Furthermore, every other quota that has multiple answer options 'if selected' doesn't work (as you can see on the left).

Check if the customized option is set correctly or not, like what to do if quota has been met. Also use the same logic to punch an embedded variable and see if the value you set gets updated for the new variable or not.
