# Cannot have a reference in recursive expresion greater than 9 [closed]

Hello,

I have been trying to parse the output of the lightning calendar using libre office calc. I have a cell with the following content:

20120522T130000 and I have to make it look like this 22-May-2012 13:00:00

so I used search and replace with recursive expressions selected and wrote Search: ([:digit:])([:digit:])([:digit:])([:digit:])([:digit:])([:digit:])([:digit:])([:digit:])T([:digit:])([:digit:])([:digit:])([:digit:])([:digit:])([:digit:]) Replace $1$2$3$4/$5$6/$7$8 $9$10:$11$12:$13$14

And I get 2012/05/22 120:20:2122:2324

so I try the obvious choices of grouping the 1? with parenthesis, braces and brakets but I get 2012/05/22 1$(10):$[11]${12}:$(13)$[14]

Is there any way to pass references higher than 9? (I would assume so)
