steps to debug an action
1 check it visually to make sure all the ids idnext and parameters are filled in properly
2 run the action and check where it stops
3 check the tasks and confirm they match the actions
"this doesnt work" wont give anyone enough information to help you.
if you make it to step 2 and cant figure out where it stops you can post that portion of your action here
and someone may be able to help you sort it
