I cant figure out whats wrong with this update statement...

declare @Resell_program table (TC_ID nvarchar(max), ind_1x_res_id nvarchar(max),ind_1x_res_product nvarchar(max), ind_1x_res_current nvarchar(max),ind_1x_res_SUB_TOTAL nvarchar(max) ,ind_1x_res_TOTAL nvarchar(max))
insert into @Resell_program (TC_ID,ind_1x_res_id,ind_1x_res_product,ind_1x_res_current,ind_1x_res_SUB_TOTAL,ind_1x_res_TOTAL)
values ('TC_ID_SD9FJG3K','IR_1X_WEDR5T','PRO','YES','','')
SELECT * FROM @Resell_program

UPDATE RS
SET ind_1x_res_SUB_TOTAL CASE =
WHEN ind_1x_res_product = 'PRO' THEN '1'
WHEN ind_1x_res_product = 'H' THEN '8'
END
FROM @Resell_program RS
WHERE TC_ID = 'TC_ID_SD9FJG3K'
