Thank you for the suggestions! To clarify my situation, I'm working with an attendance form that has over 45 rows to accomodate different activities, and 16 columns to accomodate each day in the timeframe (1st to the 15th, or 16th to the end of the month). I want the attendance form to be as uncluttered as possible, so I'm looking for a way to automatically hide the rows (row height=0) that aren't being used, and to automatically hide the columns (column width=0) that aren't necessary for the current timeframe (i.e. the last 3 columns when the timeframe is February 16th to February 28th).
For simplicity sake, let's say the range is rows 1-10, and I'm trying to individually hide rows where the cell in the A column contains the word "HIDE".
Thank you in advance for any help you can provide!
