InputBox String Conversion

I am trying to let a user select a range, then search the range against a second range for identical values. I'm having difficulty using the input in the macro, specifically finding where the range begins, and the length for my for/next statements.

HTML Code: 

I'm pretty new to this, trying to hack this code together from previous posts. Thanks to those authors!
Any help?

Why do you need to find where the range starts?

Can't you just loop through it?

For Each c in myRange ' loop through each cell in the range
    ' code for working with each cell
Next c

that's why you answer the questions, and I only ask them. Thanks, that worked, it cycles through every cell in the range. Follow up question: the range I'm using is several columns wide, I'm only interested in looking at one column for now. How would I only cycle through column B if the range is A1:D7, for instance?
Thanks

I don't quite follow.

You are letting the user select the range but then you want to specify the range to work with.

Well, I want the user to select the range, but that macro will need to run through the range a few times and look at a few columns independently to trigger other if/then statements. Does that make sense?
