Hey guys,

Im trying to put together a regular expression to search through a string for letters in a spacific place in the string....for example, if im looking for "o", "a" and "s" in "boards", i would have to put in "o1", "a2" and "s5"....

Heres what i have already but it wont work:
val4.append("[" + letters.get(x) + "]" + "\\" + numbers.get(x));

val4 is a StringBuffer that is appended for every segment (i.e. "o1" etc...)

I get this error: "No such group yet exists at this point in the pattern near index 9"

It looks like this in the output: [o]\1[a]\2\5

Cheers
