My form allows users to put in a depth value (decimal) for each station (text box) they assign (max of 40 stations). I need to be able to calculate the average of the total depth. In my attached image, you can see I'm using an IF statement to determine how many stations they provided a value for so that I can divide that number by the total depth BUT the average is not dynamically showing as they add another station. Can someone let me know what is wrong with my logic or if there is a better way? Thank you in advance
