Data entry form - Duplicate searching

[Macroni and cheese]

Hi all!

I'm creating a data entry user form in VBA which allow the company to input/modify/remove staff members.

Each staff member has a unique ID number.

Can someone help me with a code that searches through the existing data (once they have left that textbox in the user form)to identify if the unique ID is due to be duplicated?

I'm then hoping for a pop up box to prompt to ask the user if they want to continue (Y/N) and an option to take the user to the existing Unique ID number.

Userform = AddPerson
Worksheet = Sheet1
Textbox = Staffno

Thanks in advance!!

You would just use the Exit event for the Staffno textbox. After that, it's just a loop through the table to look for a matching ID number.

For input of a staff member, an if statement inside the loop will check for a match; warn user of the duplicate ID and Exit Sub

For checking duplicates during modify, the loop should go all the way to the end of the data and count the number of matches found; loading the row number or address of the most recent found. If the count is more than 1, warn user of the issue.

For removal, it can be the same as the modify to make sure the correct staff member is being removed.

I think your best option would be to use a the VBA find function to check for the ID exist. You can apply this to the Change event of the text box
