How Can I make a Macro work to Hidden Sheets?

[mrgillus]

OR can I? I get a "Run Time Error '1004' Select Method of Worksheet Class Failed"

Is there anyway around this?

Basically all the sheets are hidden from the user except for the Entry sheet. They input there data on there and then they press a send command button which then needs to copy that information to a hidden sheet. This is where the problem occurs.. Thought maybe their was a way around that or do I need to unhide the sheets during the macro and then rehide them again?

Thanks for the advice!
