• Reverse - Link Cell to Textbox

  - by Daniel

  I have 5 worksheets and a textbox on each worksheet. I would like all the textboxes to display the same value, which would be whatever the user enters in the first textbox. So once a value is entered in textbox1 on sheet1, textbox2 on sheet2, etc. will be populated with the same value. I'm looking for something like changing linkedcell =WorksheetName!textbox1 although I'm pretty sure that is incorrect.

I understand the concept of "if it ain't broke, don't fix it" but when does that become losing pride in code you've already written and what does it say for refactoring.
