Question: extracting numeric values from pdsolve value

I've solved a PDE with pdsolve, I can get the value of u(x,t) at a certain x and a certain t with the value command, K := pds:-value(x = 1-b, t = 0 .. 1, output = listprocedure) leads to; [100.*(x(0) = .99), 100.*(t(0) = 0.), 100.*((u(x, t))(0) = 2.40908278321669992*10^(-93))] id like to get the u(x,t) value out to put it in a function, is there a simple way of doing this? Thanks, Ryan
