Error, (in Optimization:-NLPSolve) integration range or variable must be specified in the second argument, got 1. = 1. .. 1.

Hi, I'm new to Maple and trying to use the minimizer to find the values of 'u' and 'b' that get the value of my objective function as close to 0 as possible (I therefore take the absolute value of the function before minimizing).  Above is what I have and the error I keep getting.  I would really appreciate any suggestions.  Thanks!

Here it is if it's not showing up above:

NLPSolve(abs(int((1-x)*(1-(.2*u*(1-u)/(x*(1-x))-.2)^(1/4)), x = b .. u)-0.05), {b>=0, b<=u})

edit:

I have also tried the Int command as the inert form of int since the integral has no closed-form solution.  When I try this I get a different error:

Error, (in Optimization:-NLPSolve) invalid arguments
