What is the wrong in this code?

I use this code in a class to insert row in table:-

'********************
Public Sub hosptINSERT(FRM As Object, C As Object)

Set Cmd = New ADODB.Command
With Cmd
.ActiveConnection = cn
.CommandText = "prd_insert_HOSPT"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("@HOSPNAME_1", adVarChar, 1, 10, C(0).Text)
.Parameters.Append .CreateParameter("@FULLNAME_2 ", adVarChar, 1, 50, C(1).Text)
.Parameters.Append .CreateParameter("@AHOSPNAME_3", adVarChar, 1, 50, C(2).Text)
End With
End Sub
'********************
WHEN I TRAY TO RUN IT ,I FACE THES MSG:-'Must specify index for object array'

which line does Debug give the error on?

you don't say what "cn" is. Is it an object array?

The object array is c(0),c(1) and c(3)

0, 1 and 3??

So what can i do? How can i solve it? i need it to work in a class.

What is your code when you call this "hosptINSERT" sub?
