Cannot assign starting IP address

[ozzie14]

I am about to finish this packet tracer lab, but the only thing is that the wireless router is not letting me finish is that the starting ip address for the DHCP server should be 10.10.10.50 and when I try to put it, it will automatically change to 10.10.10.1. 

I checked the subnetting and everything is fine.

does anybody knows a way to assign it without automatically change it?

This is PacketTracer limitation. If you use mask 255.255.255.0, it will accept the configuration but as you are using 255.255.255.128, it will use the first IP for the DHCP range.
