Must declare variable.

I am fairly new to ASP.Net. I am encountering an error:
Must declare the scalar variable "@equipmmenttype".

I am not sure where or how I need to declare this.
Any help would be great. Thanks in advance !!

CODE:

<%@ Page Language="VB" %>
<script runat="server">

Protected Sub DetailsView1_ItemInserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertedEventArgs)

If (Not e.Exception Is Nothing) Then

ErrorMessageLabel.Text = "An error occured while entering this record. Please verify you have entered data in the correct format."
e.ExceptionHandled = True
End If
GridView1.DataBind()
End Sub

Protected Sub DetailsView1_ItemUpdated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdatedEventArgs)

GridView1.DataBind()
End Sub

Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)

DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
End Sub

Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)

DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
End Sub

Protected Sub GridView1_PageIndexChanged(ByVal sender As Object, ByVal e As EventArgs)

DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
End Sub

Protected Sub GridView1_Sorted(ByVal sender As Object, ByVal e As System.EventArgs)
DetailsView1.ChangeMode(DetailsViewMode.ReadOnly)
End Sub

Protected Sub GridView1_RowDeleted(ByVal sender As Object, ByVal e As GridViewDeletedEventArgs)

If (Not e.Exception Is Nothing) Then

ErrorMessageLabel.Text = "Failed to DELETE due to foreign key contstraint on the table. You may only delete rows which have no related records."
e.ExceptionHandled = True
End If
End Sub

Protected Sub DetailsView1_DataBound(ByVal sender As Object, ByVal e As EventArgs)

If (DetailsView1.CurrentMode = DetailsViewMode.Insert) Then

Dim stateTextBox As TextBox = CType(DetailsView1.Rows(6).Cells(1).Controls(0), TextBox)
stateTextBox.Text = DropDownList1.SelectedValue
stateTextBox.Enabled = False
End If
End Sub

Hai
you put 2 m's instead of single 'm'
error lines
SelectCommand="SELECT [id], [equipmenttype], [make], [model], [serial], [owner], [name] FROM [hardwareinventory] WHERE ([equipmmenttype] = @equipmmenttype)"
