i have no idea how i'm trying do.
data relationships demonstrated in example

update sym_entries_data_55' set value =  '46.00'  (sym_entries_data_55.id = sym_entries_data_54.id) , (sym_entries_data_54.member_id = sym_entries_data_5.entry_id) , (sym_entries_data_5.username = 'namehere')

answer

update sym_entries_data_55, sym_entries_data_54, sym_entries_data_5     set sym_entries_data_55.value = '52.00'     sym_entries_data_55.id = sym_entries_data_54.id         , sym_entries_data_54.member_id = sym_entries_data_5.entry_id         , sym_entries_data_5.username = 'namehere' 

update sym_entries_data_55, sym_entries_data_54, sym_entries_data_5     set sym_entries_data_55.value = '46.00'     sym_entries_data_55.id = sym_entries_data_54.id         , sym_entries_data_54.member_id = sym_entries_data_5.entry_id         , sym_entries_data_5.username = 'namehere'
