I have created the following SAS table:

```
DATA test;
INPUT name$ Group_Number;
CARDS;
Joseph 1
Stephanie 2
Linda 3
James 1
Jane 2; 
run;

```

I would like to change group number from a character type into a numeric type.

Here is my attempt:

```
data test2;
set test;
Group_Number1 = input(Group_Number, best5.);
run;

```

The problem is that when I execute:

```
proc contents data = test2; 
run;

```

The output table shows that group number is still of a character type. I think that the problem may be that I have "best5." in my input statement. However I am not 100% sure what is wrong.

How can I fix the solution?
