event sheet posted in a link, see link above.

when i use alert, all the element displayed, but when i add myarray.currentvalue=18 it doesnt work, i wonder why.

i alert all then element, it contain number 18.

but it doesnt work in the myarray.currentvalue=18 condition.

Make sure your data is not actually strings. People make this mistake. It will look like 18, but "18" is not the same as 18. Can't be more help without seeing more code.
