Specifying file name when saving using VBA in excel returning a blank

I am trying to get this code to work but when the save dialogue opens the suggested file name is blank. I traced the variable "saveFile" in the locals window and it's false instead of the string value. I'm not sure why.

Simply, I want the file name to be the suppliername followed by the word batch add and then today's date.

Thanks is advance
