If statements within a while loop with user input

This code was working earlier, but now I'm having issues with the while 0 <= int(relationship) > 3 block of code. The user should be able choose the type of relationship to the letter recipient, which will populate a salutation and valediction into a letter.

If I keep the if/elif statements within the while loop, the sal/val strings don't populate into the letter.

If I bring the if/elif statements flush with the while loop, the strings populate for the letter ONLY if the user types 1, 2, or 3 on the first time around. If the user types a number besides 1, 2, or 3, the program will continue but the sal/val strings will not populate.

Originally, I only had one set of if/elif statements, but I created two (which is redundant, and also not fixing the issue) sets of statements to see if that would solve the problem. I've messed around with indentation as well. I also tried creating functions for each type of relationship, but I kept getting name errors for salutation.

I can get the program to work if the user follows directions the first time around, or have it run if the user is prompted to type 1, 2, or 3 after mistyping on the first try. But I can't get the sal/val to populate in both cases. I feel like the issue must be related to indentation, but when I change the indentation levels, the problem is't solved.

The output should be something like:

,boB raeD

!doog m'I ?uoy era woH

!!uoy ssim I

,yllaidroC

.em llaC .S.P

But the Dear and Cordially, are not populating if the user types something besides 1, 2, or 3 and has to be prompted a second time.
