Try converting the string to a type "double" or "single" or "integer" like this:
<%c = cdbl((8 + 7) /3)%>
cdbl for conversion to type double
clng for long
cint for integer
Check this with <%=c%> and you should get 5.
<%Cdbl(c)%> doesnt work since c is already a string! You must make the conversion at the same time you are setting c.
Hope this helps.
