Sum all cells meeting condition

i have a very large spreadsheet so i am trying to find an efficient way to accomplish what i am working on.

in column sz, there will be one of 31 text options that will be inputted down the 1000 rows. what i need to do is a simple statement, non VBA preferably, that will sum all of the cells in column H if the corresponding cell in column sz = "option 1"

i have been able to do it by doing a simple if statement with A LOT of helper columns but this bogs down the system WAY too much as i have approximately 50 columns that i need to do this for each of the 31 options. i did this on a separate worksheet and went past column BAA so i very much need a quicker and more efficient way. anybody have any thoughts?

thank you for any help
