Include Txt to a certain character in a string

I have the following EDI message and have the following statement in a query;  

Units: Mid([swift],InStr(1,[swift],":36B::SETT//UNIT/")+17,12)


In this particular line, the number of characters is variable until the ','.  So what I need to do is bring in 3493 in this case but if it was 99999, then I would need to bring in 99999 and so forth.  It is whatever value from the / to the ,.

The above code is bring in characters from the next line.   How do you stop at the ','?

I was trying the charindex function but without much luck.  Any ideas?

Do you always look for the FIRST instance of the comma, and the get all characters BEFORE that comma up to the preceding slash?

If so, you can do this:

Units: mid([swift],Instrrev([swift],"/",instr([swift], ","))+1,   instr([swift], ",")- Instrrev( [swift],"/",instr([swift], ","))-1)
