Hello I have a chart on my workbook. I am trying to format the TickLabels

Produce Letters instead on numbers, it only changes two numbers. and then
give a error

value on the
TickLabels to change will be appreciated. Thanks

Selection.TickLabels.NumberFormat = "[=19] ""G""; [=17] ""S"";[=17] ""F""; "
