yes I had realized this already but I still don't know how to get those page numbers down into MP - they keep being strings with macro code instead is there a way the I can get \setupMPvariables[hdrPgs] in \setupheadertexts[\setups{page:header}] to be fully evaluated and stored as the page number in the MPvariables first= and next= ?? \startsetups page:header \setupMPvariables[hdrPgs] [curr=\pagenumber, first={\ref[page][\headerfirst]}, next={\ref[page][\headernext]}] I've tried \expanded and \numeric without success or alternatively in MP how would I call TeX (from MP) with a string like "\ref[page][a]" and have the page number stored in a numeric var?
