disable options in multiselect

Hi All,
I have a multiselect drop down . At first users lets think it is "new" mode users will submit this multiselect drop down and value/values will be stored in database( I have 5 values in drop down)
now in "update" mode again users will try to submit by selecting more values from this multiselect drop down, but I want to stop and show them a alert as soon as submit all the values in the drop down , i.e out of 5 they can select upto 4 , but if they select the 5th one ,I should leave the values which came from database and I should deselect recently selected values.
I hope I am clear.
Thanks in adavance.

Why not generate a checkboxes list instead? Which i think more user friendly and easier for your scripting?

Iterate through selected values, check size and show alert.
