I am getting An unhandled exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll

Additional information: Conversion from string "Regular" to type 'Integer' is not valid.

I tried String then Integer the thing is it's just a combobox with two choices NFC OR AFC. WHY IS THIS HAPPENING HERE IS THE INSERT
 Public Sub Insertdata()
        Dim strplayerid As Integer = CInt(txtPlayerID.Text)
        Dim strTEAMID As String = CStr(txtTeamID.Text)
        Dim strSEASON As String = CStr(txtSeason.Text)
        Dim strPOSTSEASON As Integer = CInt(cmbPassSeason.Text)
        Dim strConference As String = CStr(txtConf.Text)
        Dim strAttempts As String = CStr(txtatt.Text)

I don't know where the problem is - VB or MS SQL Server.

Assuming the problem is with SQL Server, try one of the following:

CAST(<<my expression>> as smallint)
CONVERT(smallint, <<my expression>>)

If you are using SQL Server 2012 or 2014, then use the following:

TRY_CAST(<<my expression>> as smallint)
TRY_CONVERT(smallint, <<my expression>>)

It will convert it to NULL if the value is not an integer.

It looks like the table field storing your value AFC or NFC is set to store an integer - and AFC/NFC is not an integer.  Check in the table definition in the database.

Just a wild guess, but since you are storing player stats, should you be storing conference in the Comp field? Isn't that Completions?

In your posted code above, line 32, you are assigning strConference (which I am inferring is NFL/AFL) to @Comp (which you say is completions, an integer value). Is that what you wanted?
