Find what the data type is for these columns:
T0.Mouldqty
T2.Rate
T2.DieSetting
T2.ChartType
T3.fid
T1.U_od
T2.SizeFrom
T2.SizeTo

If T2.ChartType = T3.fid either are a numeric change it to character (I suspect ChartType is character and fid is not)
SQL will try and make characters into a numeric if used in combination with a numeric.

Since T0.Mouldqty * T2.Rate + T2.DieSetting is an equation if any are not a numeric type use the CAST or CONVERT function.

If any T1.U_od BETWEEN T2.SizeFrom AND T2.SizeTo are character I would change to numeric.
