Clear range of columns where row is known (J to BC) and row is a variable

Thanks for any help on this.
I want to programmatically clear the contents of a row in Columns J to BC where the row number is a previously-derived variable.
I have tried variations on something like this - R is the row variable: Worksheets("C1").Range ["J" & r]: ["BC" & r].ClearContents
but none of them work.
Grateful for any assistance.

Thanks TMS but your solution has a floating open square bracket. I tried some variations but no success yet. Casn you suggest something?
Thanks

Sorry - should be Croydon

Hi TMS
I did reply to your above email (but it must have got lost) to say that I tried your solution in the command:
Worksheets("C" & cat).Range(Range("J" & cfel), Range("BC" & cfel)).ClearContents
(Variables cat and cfel contain integers eg 1 and, both declared at start of sub routine)
but all I get is an error message "Application-defined or object-defined error".
I must be doing something wrong but cannot see what.
Can you help again?

Thanks TMS. I looked into the Error 1004 question on the web; it seems to give a lot of trouble to many people. So far I have not come across an answer. Meanwhile I can get round my problem by clearing each cell individually.
