That makes sense actually! Since I was only trimming off the top to test it, the invalid one would've always been 10 from the bottom. Sorry and thanks!

Ellie, we believe this was due to an invalid postcode causing it to stop. It should now continue processing postcodes, ignoring the invalid one. Bug fix has been applied.

Unfortunately it looks like the tool had broken as of the 18th-Oct update. If the list of postcodes is longer than 10, it will get 10 away from finishing the list and freeze.

Excellent tool for helping us sort out our drivers. Only potential improvement would be an option to sort the list by travel time rather than raw distance since that can be a minor factor in some cases

This is a great tool. I think someone asked this previously, but didn't expand on it. Would be wonderful to be able to pop in say 10 postcodes at a time for the final step to speed up the result. However I have no clue how easy/complex that is. Fantastic tool and incredibly helpful.

Hi, I'm not sure I understand. So you wish to run multiple searches at the final step instead of one at a time?

Is there anyway of Feeding In Multiple Postcodes to Already Plotted List? - this tool is bloody amazing

This let me allocate potential customers to the closest rep. Many Thanks!

Excellent function to be able to identify which volunteer driver lives closest to the passenger that needs picking up. Thank-you.
