CONCATENATE and Cell Formatting

Can a cell be formated when concatenate is used? When the 2 cells are combined I am getting an unwanted result.
Example (.005 combined with .006) is giving a result of ( 0.005 0.006). I just need values to the right of the decimal.
Traditional custom cell formatting doesn't seem to work.

Thanks Jeffrybrown I will give that a try...and also post these type of questions in the correct forum in the future.
