Leaders Plymouth were also held to a draw, while third placed Bristol City continued their woeful run of late with defeat at Port Vale.
And the Rangers boss was pleased with his team’s performance throughout, despite Luton's gutsy display.
“It was a quite an exciting day. The crowd made a lot of noise. Full credit to Luton with all the injuries they’ve got.
“I’m a little disappointed that we didn’t get that second goal – but when you look at the other results – it’s another game gone and all to play for. Watch this space!
“I expected Martin Rowlands to get more of the ball – but Kevin Gallen was great today. He steadied himself for the cross for the goal.
"As for Jamie (Cureton) – he’s champing at the bit to get on and get involved. But I’ve got a lot of choice and I like being in that position.”
Ollie also made special mention of Lee Camp’s continued good form. The on-loan shot stopper continues to impress following his fourth appearance in a Rangers shirt.
“He’s a very confident lad. He’ll have a bright future. The lad has made some very good saves in the second half – but what I don’t like is that Luton had too many shots on goal in the second period. We have to shut them down.
“But all in all I’m really really looking forward to the run in – and we all should be. Everywhere we are going at the moment we are selling out. And that says a lot about what is going on here.”
