Mark chapter as cmplete with tick?

I am trying to achieve the same thing but am having a problem with getting the ticks to display.My course is setup in 3 chapters, Main Menu, Module1, Module 2The variable I have setup is Module1_Done, Initial Value 0 and retain variable value between sessions.At the end of each module I have an action on the next button:On Show: Modify Variable: Target: Module1_DoneValue: 1In debug mode it seems to be changing the variable to 1.Action [ShowTick on Black Cutout Next] fired!readVariable for Module1_Done = [0]saveVariable for Module1_Done to [1]In my Main Menu Chapter I have and action group with the action Module1_Done. Action: Show, Target: tick1 (which is a wmf graphic file)Condition: Variable Module1_Done Relationship: Equal to Value: 1. I have the graphic file located within the action group. I then have an action outside of this to run this action group.In debug mode it gets as far as:---- Main_Menu ----Action [Run_Module_Status_AG on Main_Menu] fired!Action [Module1_Done on Module_Status] fired!But no tick appears.I have tried having the tick initially visible and not. Still nothing.I am pretty new to Lectora and hope that what I have put here is making sense and that one of you experts out there can help me. Any advice will be greatly appreciated! Thanks Karen
