2nd Userform not populating information

[emeralds]

Hi All, I am very new to excel VBA (Came acrros this function 2 days ago) and as such i am really lost as to how to fix some things.
I have been able to get everything working except for a couple of things and I am so stumped on how to fix these

I have a button in my worksheet to open the userform and create a new entry (This works), then I created a second button linking to a second userform that is suppose to

1. Check for text input in textbox (on excel page) and see if it exists in another sheet (i.e., a user ID - This function works)
2. Open the second userform (this works)
3. and populate existing data in the userform for updating (This does NOT work/ I cannot work out what code to put here.

Point 3 is where I am having issues, code sample seen below.

The form contains a mixture of text boxes and comboboxes.

Any guidance is greatly appreciated! (also if you need further information etc please let me know)

I also forgot to mention that the Combo boxes for the second userform are not populating (They are however for the first userform)
