Cannot connect tracks to pads

Designed a ATTiny88 symbol and footprint.
All checks out but I have missed something as I cannot connect tracks to the ATTiny88 in PCB editor.
Kicad V8.

Did you skip making a schematic?

No, made a schematic and checked it with the footprint.
All seemed well. I did design the symbol and footprint.

But you didn’t give your symbol pin numbers so there is nothing to match to the pin numbers on the footprint . . .

Thanks, do the pins in the schematic have to match anything or can they be random?

The symbol pin numbers (and function) must match the footprint pin numbers (and function).

The symbol is “symbolic” it can be square, triangular, hexagonal . . . but it needs to have the correct number of pins and with the correct numbers.
