NEED HELP with fortran compiler ASAP

[shenie]

I am having trouble compiling code. Here's my code:

PROGRAM Sample1

IMPLICIT NONE
! Variables and constants
INTEGER, PARAMETER :: n=1000, m=10
INTEGER :: i
REAL, DIMENSION (1: n) :: x
REAL, DIMENSION (1:100, 1:m) :: y
REAL, DIMENSION (1: m):: colavg
INTEGER :: filestat, IO_stat_num


! Open file and Check for error

OPEN( UNIT=10, FILE= 'Data1.txt', IOSTAT=filestat, STATUS='OLD')

IF (filestat>0) THEN
PRINT *, 'Error opening file. Error Code: ', filestat
STOP
ENDIF

DO i=1, n

READ (UNIT=10, FMT=101, IOSTAT=IO_stat_num) x(i)
101 FORMAT (2F8.3)

IF (IO_stat_num == 0) THEN
CYCLE
ELSEIF (IO_stat_num == -1) THEN
PRINT *,'EOF at line ', i
EXIT

ELSEIF(IO_stat_num > 0) THEN
PRINT *,'Non numeric data at line ', i
EXIT
ENDIF
ENDDO
CLOSE(UNIT=10)
! call sorting routine from book

CALL shell (n,x)

! Create ten averaged bins

y = RESHAPE(x,(/100,10/))
colavg = sum( y, dim=1)
colavg = colavg/100

OPEN(UNIT=20, FILE='Bins1', STATUS='NEW')

WRITE (UNIT=20) colavg

CLOSE (UNIT=20)

END PROGRAM Sample1

SUBROUTINE shell(n,a)

INTEGER n
REAL a(n)
INTEGER i,j, inc
REAL v

inc=1
1 inc=3*inc+1
if(inc.le.n) goto 1
2 CONTINUE
inc =inc/3
DO i = inc+1, n
v= a(i)
j=i
3 IF (a(j-inc).gt.v) THEN
a(j)=a(j-inc)
j=j-inc
IF (j.le.inc) GOTO 4
GOTO 3
ENDIF
4 a(j)=v

ENDDO

if(inc.gt.1) GOTO 2

RETURN
END

PLEASE HELP

It appears to be compiling two files: simple.f95 and sample1.f90.

Which gives it two _MAIN_ modules which the linker doesn't like.

Is there something wrong with your make or project file?

Thanks..I didn't realize it was trying to compile 2. My first time using fortran.
