We have a number of Custom reports that require some user paramaters to be inputted for selection criteria. these reports was originaly written in crystal 8 and accpac 5.4 over the years the reports has been updated without an issue and even the change from pervasive to Msql was not an issue until we got now to 2014 all of a sudden the parameter screen does not allow you to select a single item eg location A1  in parameter loc_str and location A1 in parameter loc_end, if you put in loc_str =A1 and loc_end=B6 the report works perfect.( the error is missing parameter)

When i ran and tested on my own laptop with there data i do not receive the same problem. same Crystal 11 install files used the only difference laptop win 8.1 and there server server 2012

Anyone with any ideas?
