Friends I'm a beginner for Excel VBA. Here is problem. Currently I'm leading a team. I have Part numbers in Colum "A". And I have Part name in Colum "B", and I have estimation hours in coloum"C". Now I have created an Form with the text box and command box (Please see the attachment"). Which will display the values for Colum “A”,”B”,”C”. When I ran the macro seem all the values are pulling correctly however I want the user can not edit the values showing the text box. Can any one help me in this
