The start of this condition ("{ if ") is not an expansion action. It
should be "${if". If you do that, you'll get a syntax error, because the
sub-conditions inside your "or" are not valid subconditions. If you want
to do it this way, you have to write

  condition = ${if or                     \
               {                          \
               {eq {${lookup....}}{yes}}  \
               {eq {${lookup....}}{yes}}  \
               }                          \
               {yes}{no}}


But you don't need to do this. You could also do

  condition = ${lookup ... {yes}          \
               {                          \
               ${lookup ... {yes}{no}}    \
               }}


In other words, put the second lookup in the "fail" argument of the
first lookup.
