Does VBA for Excel not allow nested while loops? I don't write macros all that often but whenever I do, I nest a while loop (because I forgot that it didn't work last time), it errors out and I end up ...

i'm trying to write vba code so that a range of cells (from A2 to Ax where x is variable) will be filled with a series of receipt numbers with the user only needing to input the first receipt number ...
