VBA: How to handle dynamic ranges with undefined boundaries in a loop?

Excel VBA dynamic-range

Could someone explain I'm sure I'm missing something obvious here, but I'm dealing with I'm trying to implement I'm relatively new to this, so bear with me... I'm working on a VBA macro that needs to iterate through a dynamic range in Excel where the boundaries can change based on user input. Specifically, I'm trying to process data in a column which may have varying lengths, depending on the user's input. The scenario arises when I attempt to set my range for a loop.\n\nI've tried using the `End` property to find the last row in the column, but it's returning an unexpected result. Here's a snippet of my code:\n\n```vba\nDim lastRow As Long\nDim myRange As Range\n\n' Assuming the data is in column A\nlastRow = Cells(Rows.Count, 1).End(xlUp).Row\nSet myRange = Range("A1:A" & lastRow)\n\nDim cell As Range\nFor Each cell In myRange\n Debug.Print cell.Value\nNext cell\n```\n\nHowever, when I run this code, I sometimes get an empty range or it processes fewer rows than expected, especially when the last row of data is far from the bottom of the column. I'm also concerned about potential empty cells in between the data. Is there a better approach to dynamically define the range without missing any data or processing empty cells incorrectly? Also, what would be the best way to handle cases where the user clears some input, resulting in fewer rows?\n\nI'm currently using Excel 365 and have tried adjusting my range definition, but I keep running into these inconsistencies. Any suggestions on a more robust way to handle dynamic ranges would be greatly appreciated! For context: I'm using Vba on Windows. This is part of a larger mobile app I'm building. Has anyone else encountered this? This issue appeared after updating to Vba stable. This is my first time working with Vba 3.9. I'd love to hear your thoughts on this. I'm working on a application that needs to handle this. Could someone point me to the right documentation? I recently upgraded to Vba 3.11. Has anyone dealt with something similar?
