I was surprised to find three or four code samples that did a similar thing as below, but was unable to adapt the monsters to my sheet.

Here is what I want to do.
With columns A & B:

Change this

GL14 x
GL15
GL15
GL15
GL16 x
GL17
GL17


to this

GL14 x
GL15 3
GL16 x
GL17 2

Whe if there is text in column B leave A and B as is.
Whe there were three GL15's before, reduce to one GL15 with a count of how may there was to begin with.

The codes I could find were pretty much multiple employee ID numbers in A and hours worked in B, then add all the hours for same ID and return a single ID in A and the total hours for that ID in B.

Thanks.
