Subtracting from drop down list

[enriquep22]

Good afternoon Folks,

I have run into a small issue using Excel. I have created a drop down list, and i'm trying to figure out how to subtract how many times a name were to come up. for example If i have 35 tickets to the movie jumanji, If i select from the drop down list Jumanji could i now get 35 to be 34? If i can please get some help with this that would be greatly appreciated.

thanks in advance,

Enrique

Give this a go.
I assume the drop down with the movie list is in cell B2.
Cells E1, F1, G1 have the movie titles in them. My movies names are "aa", "bb", "cc".
Cells E2, F2, G2 have the number of ticket available for the respective movie names.
Selecting a movie name in B2 drop down will subtract 1 (one) from that movie ticket count, until one remains, where you will get a message, and when there is 0 (zero) tickets you will get a message.
Further selection beyond 0 (zero) will count in the negative, how many you sold?... but do not have.

Copy to the sheet module where you have the drop down with the movies.
