I insert one excerpt macro and embed one HTML macro into it on page A, the excerpt displays the value of HTML macro(550) correctly on page A; On page B, I inserted on excerpt include to include excerpt on page A, but it shows NaN on page B, BTW,the value has been transferred to string format, I also tried to output the value direct in JS but it is not available in JS currently after checking(if you know a way to do so, be sure to tell me, thanks in advance). Here attached screenshots of page A and page B for details.
Page A with excerpt:
