Im working in dynamic form which shows certain items depending on the selections made by the user. What I do is make invisible the objects if certain conditions are achieved or if the user made certain choices.

I made something similar in the past with good results. On that ocasion I was changing some questions in a poll depending if the user answer "yes" or "no". But In this project I DONT KNOW WHY IT IS NOT WORKING.

The object which is a drop down list becomes visible when it is suposed to but it says "visible" and it does scroll down the choices but no matter which one the user click onto, at the end it will say "visible" and if I print the form, It will be printed with the "visible" leyend rather than the desired choice of the drop down list.

Next is part of the code:

if (Product_Service==1 or Product_Service==5 or Product_Service==6 or Product_Service==7 or Product_Service==10 or Product_Service==11)
then
Paper.presence = "visible"
Impresion.presence = "visible"
else
Paper.presence = "invisible"
Impresion.presence = "invisible"
endif

I will apreciate any feedback on this issue.
Thanks in advance guys,
Oscar
