Can't use lookup function and cant create uniques values

Hey everyone.

I am using a Field from a raster dataset in raster calculator. Because this field is not selected by Default, I have to use the lookup function to make the program select this field.

I type the following in raster calculator.

Lookup("ESACCI-LC-L4-LCCS-Map-300m-P5Y-2010-v1.4.tif","Perc_fores").

"Perc_fores" is a long integer that I have created and this is the field that I need for my analysis. However, this gives an error in the look up function.

 

When I try the same for the "Count" field so written as below:

Lookup("ESACCI-LC-L4-LCCS-Map-300m-P5Y-2010-v1.4.tif","Count")

, then it works fine.

 

But if I try on the "Value"

Lookup("ESACCI-LC-L4-LCCS-Map-300m-P5Y-2010-v1.4.tif","Value")

, then it doesn't work either.

 

I have checked that everything is correctly spelled and so on. What can the reason for this be? I have used the lookup function a thousand times and it has always worked.

 

Thank you very much.

best regards
