how to select more than one from a select menu?

[John Herdean]

something happened to that localStorageItem 'interest_music' - it got deleted somehow. I have no idea how, but it did. about a couple weeks ago i had a bunch of Set Property Events also deleted from a page somehow.

Hi John,

Are there any other problems with the app integrity?Are you sure you couldn't delete them or elements connected with them?

[John Herdean]

ohh, BTW let me mention that there are a bunch of predefined items already stored on the front-end select menu. So, the only thing im looking to do is to just have whatever values come in to just be checked off, and not change the items already there. The same way i was able to do with the localStorage values earlier.

well im not 100% if nothing else was connected to it and got deleted, but im sure that I didnt delete the localStorageItem directly

Regarding the 2nd problem (storing the results from aws server to local storage - from previous posting), this i finally got to work.

this is how i mapped it 1st and didnt work:

I mapped it twice like this and works:

ok so now i just need somebody to point out what is wrong with this method of mapping? Thanks...

[John Herdean]

sorry, false alarm. the # 2 problem (localSTorage mapping) is still outstanding. Apparently, before it read from the last time i saved into localStorage directly. I thought the REST service past, but I did further tests and found out the way I mapped it last (see last image posted) actually crashed the service (it returns an error):

So, now I need help on both of my original problems. Please let me know what is wrong in each case. Thanks

how are we doing with these 2 issues?

Hi Marina, thanks for this JS. If I had a selectmenu with just a single value, what would the JS look like in that case? Thanks again.
