hiding/unhiding rows based on a selection from a drop down

Hi,

I'm trying to formulate a spreadsheet that will hide/unhide rows depending on a selection made in a drop down (list). There are 3 options in the drop down that correlate to a type of request; whichever option is selected needs to only show the relevent rows for that type. I've listed a reference in column A for each row that would need to show for the specific type of request. I'm not very good with macros but I think there might be a way to accomplish this. I've attached the document; any help would be appriciated.

Thanks!

Yes, that would be helpful wouldn't it...

1. New Account Request
- all rows unhidden
- row 9 hidden
2. New Level Add
- all rows unhidden
- rows to hide:
- 5:8
- 12:13
- 18
- 20:33
- 68:76
- 83
- 85
- 88
- 91
- 94
- 96:97
3. New User Add
- all rows unhidden
- rows to hide:
- 5:8
- 10:49
- 68:76
- 83:99

Hope this helps.

Thank you so much! That worked perfectly. I appricate the help!
