Sheet Code Not Updating with userform?

Good day all,

I have previously asked this question & was given the solution but since then I have included a UserForm to my WorkBook & now the below issue has returned & now completely gazumped? See below...

I have a sheet code ("Page 3") that based on one cell value ("D10") populates the relevant information from another sheet ("List"), the problem is this value ("D10") is generated from another sheet ("Form") & because of this the code doesn't update? Any help would be greatly appreciated, thank you all & have a great day,

Marco
