Proper Syntax when applying Temperature Field

I am currently trying to apply a temperature field in Abaqus. I am having issues when applying this in the input file. I am using a predefined field temperature input to apply this temperature field. I am running into an error where the program can not find the appropriate text file that contains the temperature field. The temperature field is set up properly in the text file however I think their is an issue with the syntax of the file name or specifying the path. Are there any specific syntax rules with specifying the name of the file or specifying the path name to the text file? Thank you for the help in advance.
