index sheet varies

hi

I have a table. In this table the name of the sheets and sheet index are written.
1 sheet1 1
2 sheet2 2
3 sheet3 3
I would like to write the following code:
sheet2.range("a2")
For example, number 2 varies. How can I use number 2 instead of the above table?

I click on each row in table, index sheet goes to cell A1. The front of the sheet number is read from cell A1.i want instead under code :

sheet3.range("e3")

use digit 3 from cell A1.
