Why not post the code instead of a screenshot of the code? People are more inclined to offer help if they don't have to create a file to test with.
sorry about that the code is like 900 lines plus, i initial thought of including it but thought it too much and confuse the reader
There's no need for the entire script. Just reduce the code to the relevant parts -- in this case all that's necessary is the part you made the screenshot from. After all, the problem you're having is with getting the set of parameter sets to work.
Also, knowing what combinations of parameters you expect to work together and those that should never be used together would be helpful.
For what it's worth, I've never found the error message that results from a parameter set conflict to be very helpful. It basically says "Oops! Something's wrong! Try guessing what combinations are allowed." I usually test the combinations in the code and throw an exception with something meaningful in the text.

Hi,
When running a function, it is worth noting that only 1 parameter set can be matched at a time.
In this case, it likely means that you either have two switches enabled at once, or "personalName" defined while you also have the backup switch enabled at the same time.
If you would like "personalName" to exist within the "Back" parameter set, you will need to add another Parameter declaration stating that it exists within that set.
This would look something like this:
[Parameter(Mandatory=$true, ParameterSetName = 'Delete')]
[Parameter(Mandatory=$true, ParameterSetName = 'BackAndDelete')]
[Parameter(Mandatory=$true, ParameterSetName = 'Back')]
[string]
$personalName
Please let me know if this works, or if you have any additional questions!
Firstly Thanks for the response, I’ll try this out. & yes I need personalname to exist
1 thing to note, this error only came about when I use the $backup only so “parametersername=back”
If I use any of the other parameter my pipeline works it’s just $backup which is erroring to that message above.
unfortunately @Justin Brickley i tired that suggestion above Justin and its not working. still same error. i tried few different methods as well but no luck.
I think all you need to do is to remove two of the "[Parameter(...)]" specifications for the "targetname" parameter and remove the ",ParameteSetName=..." from the third. The targetname is part of every other parameter set so there's no need to make it a member of any of them.
