How to Calculate percentage

Hi,I have the same problem.I want to calculate the progress of my course and present it as a percentage.What i have done is:Created a variable called varProgressMade an actiongroup where the calculation will take placeThe first action is modifying the varProgress variable with PageInTitleSecond action modifying varProgress by dividing with TotalPagesThird action is multiplying varProgress with 100 to get the percentage.Fourth action changes the contents of a textfield to show the progress.When testing the course i get the invalid message in the textfield. To me it looks like step three is the one causing trouble. If i remove this step i get a correct value. Not in percent though.Is this a bug in Lectora?I use Lectora v9a on XP.Edited By: sjostrom on 2009-3-13 6:15:43
