Book for Userforms

[amxtomzo]

hi

i am looking for a book or 2 that spends a fair amount of time on Excel Userfoms.

i am late to using these and the few have have made have improved out data entry and productivity.

but i need more, i have seen what some can do, i would like to expand on what i have seen and learned

any suggestions for books from beginner to expert would be appreciated.

as always thank you for your help

Tom
