I have had programming, but I have not done much in VB.
I am working in Excel.
I want to take input data on sheet ENTRY and add it to the next available blank line on the sheet DATA.(already did one infinite LOOP!! with a ISBLANK function) This is probably simple, but I seem to be missing something trying to do this in Excel.

Could really use some help.
Thanks
Sue
