Using Results of a Userform in a module which uses values from workbook to return a result

[excelll33]

I'm trying to figure out how to use the results from a userform, in a module which will use the results to find a value from the workbook. I.e. Instead of using multiple input boxes, I want to use a userform. I don't know how I should code the OK button on my userform to allow me to use the results in the module for returning the values. Any help would be great thanks!

Is this possible, or would it be easier to get the userform results to be saved in a worksheet, and then using the values saved in the worksheet in the module
