Refreshing Excel data

hello,

i finally made it to xcelsius 2008, but i am running into issues/differences that i can't figure out and can't find an answer to here or the online help file.

in cx 4.5, when you clicked the import model button, you had the option to refresh the data source, as well as some other options. in xcelsius 2008, these options have been removed.

i need to be able to take a spreadsheet that a user modified and/or added data to, to refresh the model.

is there a way in 2008 to let users refresh the data in a spreadsheet without my intervention?

if so, what is the name of the feature. i looked in the help file, but didn't see anything that looked like it would do what i need.

any help would be greatly appreciated.

thank you

tracy
