    Hi All

    I have a number of fields that is of data type yes/no. These fields are all questions for a questionaire to see how well someone performed. I now want to calculate what is the percentage. Thus I first want to know how to calculate the amount of yes/no answers (please note this is over different fields), then the amount of questions filled in (some questions may be N/A) and then devide the total number of "yes" by the amount of questions answered (to get the percentage of the questionaire.

    I'm new to access, and know only what is needed, so a simple answer will do.

    If anyone could help please.

    Nadia1, welcome to the Forum.
    Access registers a "yes" by storing the value -1 and a "no" by storing a 0.
