Help - SQL Keyword Error (SQLCODE -199)

I continue to receive an error (SQLCODE -199) on a statement that works in other sql programs. I have looked and looked at it, it looks fine to me. Can someone please look at the following code and tell me if you see any reason for the error? Object XSROLOTV1 in library GPSMODS not found. The error I receive is below.
Any help is appreciated. Thank you.

... SUBSTR(CHAR(DEC(LTDDAT-INT(LTDDAT/100)*100)/100) FROM 2 FOR 2)

Isn't the syntax supposed to be SUBSTR(string, start, length). The parenthesis after 2 FOR 2 ends the SUBSTR function.

Find the integer value, multiply by 100, subtract fro LTDDAT, convert to decimal, divide by 100, convert to character, then find a Substring within that resulting character string.

Maybe you only need to replace FROM with a comma, and replace FOR with a comma. the rest looks good.
