script to rename layers alphabetically

Hi everyone,

I have a renaming script that works only on numbers and I want to make it work for letters also.

What I`m trying to achieve is to select some layers --> load the script --> enter the desired name of the layer and in brackets insert the letter from where to start. Then the script iterates through the alphabet renaming the layers and adding the coresponding letter to the name and removing the brackets. For example, I select 4 layers, load the script and when the prompt comes on... enter the name:      test[C] . At the end I should have the layers renamed testC,testD,testE,testF

Any help would be appreciated!

Thanks
