How to make flint and steel on minecraft ps3?

So I just bought minecraft on ps3 since they finally got it, and i'm trying to make a portal to the nether. I have the obsidian all set up but my problem is getting the flint and steel. I have the supplies: Iron Ingot and Flint, but I don't know how to put it together. When I click on my crafting table it only opens up to the screen where you can make like wood planks, sticks, armour, doors, torches, food, etc. I can't figure out how to get to the menu where you can put the flint and iron ingot together to make flint and steel. So how do I get to that place to make it? Any help would be great! Thanks in advance! And 10 pts. To the best answer!
