Lets assume that the column you want to sum is the D column and it contains letters and numbers.So assuming you want to sum cells D1 - D25, the following formula would help you

the way this works is the first part sums only the numbers, the second part counts all of the Rs and multiplies those by 3 and adds to previous total, the 3rd part does the same accept for the Ls

You can change the ranges if you need to.

Remember that the range (D1:D25) in this example is in 3 places in the formula, to apply it to your range, you would need to change in all 3 places to be the same range.

Let me know if you have any problems with this formula or need my help further

I had to guess at the H, RH and H1 values because you didn't get back to me, but you can change the values to suit your needs. http://ge.tt/3rrTn0u/v/0?c

here is a text file containing the formula, cant possibly have a virus. And by the way the other file I sent didn't have a virus. That was a problem on your end
