It returns the ID of the 3D label with the tag Text3D:

So loading a float value to the one you store the ID of the 3D label makes absolutely no sense.

Remove this line:

pawn Code:

INI_Float("DLabel", BusinessInfo[idx][DLabel]);

In the enum you use for the BusinessInfo, change to:

pawn Code:

Text3D: DLabel,

And compile. Post those lines that give the tag mismatch warnings here.
