Why won't this fill command work?

So I am trying to use the fill command to save time on a city build but it won't work... The command looks like this: /fill 45 3 -43 -45 3 -47 and of course the block. The block is black concrete and I'm wondering if it's not able to be used for the command.

Unlike Java Edition, in PE/BE all concrete has the namespaced ID concrete. What differentiates the different colours is the data values. For example, black concrete is concrete with a data value of 15.

The data value is used after the block name in the command:

/fill 45 3 -43 -45 3 -47 concrete 15
