I am trying to publish a cdf document, but I'm having some problems with the function Manipulate with this code:
Manipulate[x + 1, {x}]
In Mathematica, when I set x = d + d^3 in the input field, I get this output:
Manipulate[x + 1, {{x, d + d^3}}]
This is what I want. However, it seems that the cdf player is only able to evaluate the expression x + 1 when x is a number and not a more complicated expression. Is this true or I am doing something wrong?
