I am using TG for V and B files (one each) processed in VPHOT. After entering the required info into TG and selecting the V and B photometry report text files which were saved to my computer I clicked on Calculate Transform Set which resulted in the following error message: "Need at least two filters data to create transforms". What are some possible causes and solutions?

Copy and paste some lines of each of your txt files so we can see what they look like.
