I am having a small issue with this formula I've been trying to figure out. I have in Column A a list of different models of coolers. In column B, I want the formula to generate a price based on each model that matches in column A. The formula that I am using is below.

=IF(ISNUMBER(SEARCH("GDIM-26",A2)),"2000",IF(ISNUMBER(SEARCH("GDM-49",A2)),"2500",IF(ISNUMBER(SEARCH("*GDM-49F*",A2)),"3000",IF(ISNUMBER(SEARCH("GDM-72",A2)),"3500",IF(ISNUMBER(SEARCH("GDM-72F",A2)),"4000",)))))

My issue that I am having is, when Column A contains GDM-49F, it still shows the same value for GDM-49 even though GDM-49F is $3000 This is also happening for GDM 72. If column A contains GDM-72F, it will show the same value as GDM-72. I hope I am explaining this well. Basically, those models, 49, 49F, 72, and 72F need to be I guess unique to their own.
