textplot.mw

I am trying to do Textplot along with numerical ode solution plots in display command but it doesnt seem to want to work, i have included my code and it can be seen that textplot works for by itself but when i want to include it into display nothing happens, any thoughts? 

Help would be appreciated. 

I am looking to solve the following ode numerically for different values of w, 

diff(y(x),x)^2=y(x)^(-3w-1), along with the intial condition y(1)=1. 

i have tried to solve this for w=-1/3 and w=0 but i am getting the error:

Error, (in DEtools/convertsys) unable to convert to an explicit first-order system

I believe it probably has something to do with the fact that the first derivative is squared but i dont know how to procede with fixing that. 

Any help would be greatly appreciated.
