Not sure how familiar you are with Excel and Vba.
And you said:
please help me how to do that because really
urgent
Learning how to build a UserForm and use it may not be something you can learn in a day or two.
On the ribbon you can choose Developer>Visual Basic>Insert>UserForm
Then you have all sort of things. You would probable only need a few textbox's and a command button
The textbox's is where your user will enter their data and when done filling in box's they would click the command button that would place the data in the sheet where you want.
Take a look and see if you think you can get a grip on this quickly.
Then tell me where you want each box's data to go to.
Each textbox has a name like textbox1 and textbox2
The Userform would also have a name. By default it would be UserForm1
To Show UserForm you would need a modulue script like this:
Code:
Sub Open_Me
Userform1.Show
End sub
Let me know if you think you can do this and if so I will give you more help.
