i'm trying to build 2-input DTL XOR gate..what is the wrong in my schematic?

 

You don't need D2 and D4.
D1 and D3 are pointing the wrong way.

You need D2 and D4 if you reverse D1 and D3, to insure that Q1 and Q3 turn off when their inputs are zero.

thank you it worked, but i'm not sure if it's DTL? sould i change it to the one in this photo(but even the one in the photo is incorrect )
