I have a form that displays the quantity of plants that we are growing by genus, (marigolds, impatiens, petunias). each genus has many different varieties that can be used to make up the mix. I need to have some type of worksheet where we can put in the total qty and calculate the quantity of each variety by putting in percentages for each variety, much the same as you could do with a spreadsheet. The results of that worksheet then needs to be saved to a table for future use. Being fairly new to Access I'm not really sure what format to use. Is there a way to display the results of a query in datasheet view minipulate the numbers and update to my table? Or am i asking for the impossible.
