# "invalid increment" message when trying to enable regular expressions in libreoffice calc [closed]

I have an existing spreadsheet that I've been using about once a year to help run an auction. The spreadsheet uses regular expressions in the "match" function. When I opened the spreadsheet to prepare for this year's auction, I discovered that the regular expressions were no longer generating matches. I then noticed under tools->options->libreoffice calc->calculate, there was a checkmark that wasn't checked to "enable regular expressions in formula". I tried checking that box and hitting OK, but calc presented a dialog box stating "invalid increment", and I was forced to cancel out of the change.

Are there any ideas on how to get rid of the "invalid increment" message so that I can enable regular expressions in my spreadsheet?

I'm running libreoffice 4.2.7.2 build ID 420m0(Build:2) on a standard ubuntu 14.04 LTS installation. If I open this same spreadsheet on a RH6 box running openoffice 4.x, the spreadsheet opens fine and all of the formulas work.

We need - minimal the problematic Formula - probably the whole Spreadsheet (without personal data) - to provide a working solution.
