That actually helps alot, as I had tried something like that. What I tried to do was:

Code:
SUM[$1] += $4*0.1

That did not work, but by storing the weights in in an array, I see how it could be workable. My only question is how to store/use multiple values.
If $2 = Homework then $4 needs to be multiplied by 0.1
if $2 = Quiz then $4 needs to be multiplied by 0.4
if $2 = Lab then $4 needs to be multiplied by 0.3
if $2 = Final then $4 needs to be multiplied by 0.15
if $2 = Survey then $4 needs to be multiplied by 0.05

Then, all I would need to do is some $4 with the new values and have the overall percent for each student.

clascl

clascl.f(3)							      LAPACK							       clascl.f(3)

NAME

       clascl.f -

SYNOPSIS

   Functions/Subroutines
       subroutine clascl (TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO)
	   CLASCL

Function/Subroutine Documentation
   subroutine clascl (characterTYPE, integerKL, integerKU, realCFROM, realCTO, integerM, integerN, complex, dimension( lda, * )A, integerLDA,
       integerINFO)
       CLASCL

       Purpose:

	    CLASCL multiplies the M by N complex matrix A by the real scalar
	    CTO/CFROM.	This is done without over/underflow as long as the final
	    result CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that
	    A may be full, upper triangular, lower triangular, upper Hessenberg,
	    or banded.

       Parameters:
	   TYPE

		     TYPE is CHARACTER*1
		     TYPE indices the storage type of the input matrix.
		     = 'G':  A is a full matrix.
		     = 'L':  A is a lower triangular matrix.
		     = 'U':  A is an upper triangular matrix.
		     = 'H':  A is an upper Hessenberg matrix.
		     = 'B':  A is a symmetric band matrix with lower bandwidth KL
			     and upper bandwidth KU and with the only the lower
			     half stored.
		     = 'Q':  A is a symmetric band matrix with lower bandwidth KL
			     and upper bandwidth KU and with the only the upper
			     half stored.
		     = 'Z':  A is a band matrix with lower bandwidth KL and upper
			     bandwidth KU. See CGBTRF for storage details.

	   KL

		     KL is INTEGER
		     The lower bandwidth of A.	Referenced only if TYPE = 'B',
		     'Q' or 'Z'.

	   KU

		     KU is INTEGER
		     The upper bandwidth of A.	Referenced only if TYPE = 'B',
		     'Q' or 'Z'.

	   CFROM

		     CFROM is REAL

	   CTO

		     CTO is REAL

		     The matrix A is multiplied by CTO/CFROM. A(I,J) is computed
		     without over/underflow if the final result CTO*A(I,J)/CFROM
		     can be represented without over/underflow.  CFROM must be
		     nonzero.

	   M

		     M is INTEGER
		     The number of rows of the matrix A.  M >= 0.

	   N

		     N is INTEGER
		     The number of columns of the matrix A.  N >= 0.

	   A

		     A is COMPLEX array, dimension (LDA,N)
		     The matrix to be multiplied by CTO/CFROM.	See TYPE for the
		     storage type.

	   LDA

		     LDA is INTEGER
		     The leading dimension of the array A.  LDA >= max(1,M).

	   INFO

		     INFO is INTEGER
		     0	- successful exit
		     <0 - if INFO = -i, the i-th argument had an illegal value.
