GRC help

I’m new to using GRC.

I put together a flow-graph, but the “Generate”, “Execute” and “Kill”
menu items are grayed-out. What am I missing?

the flow graph probably has an error:

are any of the labels on the blocks or connections drawn or highlighted
in red?

Yes.

I have a usrp_source connected directly to a de-interleave block, and
it’s complaining about a mismatch between the USRP
output, and the de-interleave input.

That’s already done. I even tried putting a stream-to-vector block in
front of the de-interleaver, but now it’s complaining
about a mismatch between the output of the usrp_source, and the
stream-to-vector block. Can I send you the
.grc (it’s not very complicated)???
