Please Help!!!While Loop and FindNext

I am trying to search the values in two columns. Since some of the values are repeated, I have created while loop to match their row. However, I got traped in an endless loop
Could someone please help me
the following is the loop

Do While fRow < gRow
Set f = Columns(3).Cells.FindNext(f)
Loop

Thanks in advance

You didn't mention in your posting what fRow and gRow are. However, since you do not change either one of them in your loop, if fRow
If you want to provide a bit more information or clarification regarding the problem you are trying to solve, I'm sure you will get lots of help with a loop that will do exactly what you want.

I am trying to create a search userform to search more than two columns of data(but two columns for now) and the data has repeated value. So, the users can enter 2 values to select a specific value or 1 value to select the first value found.
So what I did was to get the row number of two values entered by user. If those two values are on the same row select the value, if not, it loops and try to find the values on the same row
So, fRow is the 3rd row and gRow is the 4th row.
When I run the macro, I got all kinds of error messages in the last outer Else block and especially on the following two lines

Set f = Columns(3).Cells.FindNext(f)
fRow = f.Row

I have been spending too much time debugging the code and my boss is getting angry about my slowlyness. So, I haven't got much time left to finish this project
The following is the main part of the entire code, I would be greatly appreciated if you could spend some time to look over and correct any logic mistakes or syntex in there.
Thanks in advance
