I need to see a way to do the following.

I have a 2 txtboxes on a spreadsheet that when cmd button is clicked, it moves to the next available row.

I need to have a vb script that will look at last row with data and if

Lastrow with Data
column A = Txtbox1.value & column C = Txtbox2.value Then
Just add Txtbox1.value in next available row
Else
Txtbox1.value & TxtBox2.value Can both go into next available row.

Any help would be great.
