When you use drop box form fields in Microsoft Word, they may contain any variety of text and numbers to choose from. If you need to perform a calculation using data from the drop boxes, you need to add a field in which to perform it. Following that, Word has a formula feature that you may use to have the data processed and displayed in the field.
Launch Word and open the document that you contains the drop boxes you want to use to perform a calculation. Add a text box field to an area of the document to which you want the result of the calculation to appear.
Click once in the area of the document in which you want the text box to appear. Click the “Insert” tab and locate the “Text” section. Click the “Quick Parts” button and select the “Text Form Field” option, which will insert the field and open a separate dialogue window.
Click the “Formula” option in the “Field names” section. Click the “Formula” button on the “Field properties” section, which will open a separate window.
Type the formula necessary to perform the calculation, using the drop box names, following an “equal” (=) sign into the “Formula” field. For example, if you wanted to find the sum of two drop boxes, you would type “=Dropdown1+Dropdown2” into the field. Click the “OK” button to save the formula.
