The randomcoord function was given to me in the project. That's why it's not mentioned anywhere else. This is in pseudocode and I just wanted to check if there is anything wrong with it.
The program is supposed to be a game with a 10x10 grid where the player starts off in the middle and has to enter commands like up, down, left or right in order to find the antidote to the poison in 20 turns or you die.
That's the bare minimum, but I added a story and I also want to add walls somehow and I just want to know if there is anything wrong with what I have so far and if anyone is willing to help me create walls in this game.
The function of the walls would be if a player lands on that space the program would display something like "there's a wall here" and then put the player back onto the previous spot.
Can anyone help me please?

During your travels you stumbled upon the town of Ascalon. This town is full of theives, beggars, mages who practice blood magic, and a corrupted King.

You walk in and see the innkeeper at the desk and she is talking to an shady elf man. He seems to be a ranger, he has a bow on his back along with a quiver, he has long blonde hair. You walk up to the desk and ask the innkeeper for a room, she says that the only room left is on the top floor, right under the hole, Just then the elf says that you can stay in his place for the night if you need to, its in the forest surrounding the town high up in the trees.

He asks you if you would like to aid him on his quest and says that he will pay you greatly if you do so you decide to help him.

Adrian hands you a bedroll and you are so tired you immediately lay down and fall asleep.

Adrian explains to you that this was the blood mage he was looking for and he has realized he has been followed. also that he has injected you with a magic poison only he has the antidote to.
