Hi all, I'm having a number of problems when I run context on my documents I keep getting the following whenever a reference is required. systems : begin file Litreview/litreview at line 31 (./Litreview/litreview.tex ! Missing number, treated as zero. <to be read again> { \nummer ...lue {\@@thenumber {#1}\c!conversie }} { \countervalue {\@@thenumbe... \labeltexts #1#2->\leftlabeltext {#1}#2 \rightlabeltext {#1} <argument> ...anummer {\pageprefixes \pagenumber } \@@nmrechts \firstofoneargument #1->#1 \doattributes ...EA \csname #1#2\endcsname \fi {#4 }\dostopattributes ... l.4 \chapter[chap:litreview]{Literature Review} Is there any easy solution?? It happens with the bibliography as well but the final output seems correct. Adam
