writing VBA code for an excel sheet, i keep getting run time error 1004 application or object defined error.

my code reads as follows.

'Define Input variables

Dim p As Integer

Dim h As Integer

Dim sbp As Integer

Dim lbp As Integer

Dim ehp As Double

p = Worksheets("sheet1").Range("d6").Value

' [There should be five total input variables.]

'Define Output variables

Dim SEHC As Currency

Dim LEHC As Currency

Dim TSBP As Currency

Dim TLBP As Currency

Dim ECH As Integer

'Check to see if over 5 hours long

If h > 5 Then ECH = (h - 5)

If h < 5 Then ECH = 0

'Find correct number of each bus

If p > 90 Then NSB = 0 And NLB = 2

If p > 70 Then NSB = 1 And NLB = 1

If p > 55 Then NSB = 2 And NLB = 0

If p > 35 Then NSB = 0 And NLB = 1

If p < 35 Then NSB = 1 And NLB = 0

'Find extension price for buses

SE = NSB * sbp

LE = NLB * lbp

' [Now that you know the number of buses, you can figure out the extended prices.]

' [This is simply the number of buses times the appropriate base rate.]

'Calculate extra hourly charge, if any

If ECH > 0 Then SEHC = SE * ehp * ECH And LEHC = LE * ehp * ECH

If ECH >= 5 Then SEHC = (4 * ehp * SE) And LEHC = (4 * ehp * LE)

' [Here you can do some checks to see how many "extra" hours need to be charged.]

' [Remember that the number of extra hours that are charged for is capped at 4.]

'Add up the totals

TSBP = SE + SEHC

TLBP = LE + LEHC

tp = TSBP + TLBP

' [Now you just add up the various charges for the total bus prices, which also combine into the total.]
