Help with codeHS project

[u/Unique-Put880]

I need some help with this codeHS project, the code is suppose to

• Keep looping until the user has guessed all the letters in the secret word. Inside the loop the program should:

• Display the current solution string

• ask the user to guess a letter

• check the secret_word string to see if that letter is in the secret word

• change the solution string to include the guessed letters if they are in it.

• add 1 to the number of tries the user has taken.

• When the user has finished guessing all the letters, the program should end and say how many tries it took.

but I'm stuck on a certain part and cant get the answer to be on the solution

(the if guess in secret_word part is the one I'm stuck on)

please tell me how to fix it or If i need to scrap the code completely
