Excel Trigger Problem

[MICHSTEP]

I am using Vista and Excel 2007. As I write the Excel macro has just placed an in-running bet - Trigger (Instruction = BACK), Odds and Stake cells have been populated as intended. The bet does not appear on the BA interface. Checking on with the Betfair Site, the bet has not been placed.

When I was using XP and Excel 2003 with exactly the same macro, everything worked OK. Would appreciate it if anybody could give advice on this problem

Did anything appear in the bet ref column in Excel?
Does Excel appear to be updating, is cell C2 updating?
Is the trigger definitely correct, ie. no spaces before or after causing it to be unrecognised?

Nothing appears in the bet ref cell. Cell C2 is updating with the time. The "BACK" instruction has no spaces before or after.

The macro has loaded another in-running market into a different location on the spread sheet. So Excel seems to be updating and functioning OK. Macro placed a bet into this new market - which was not recognised by Betfair.

Can you send me a copy of the worksheet after the trigger is populated to admin@gruss-software.co.uk? You can remove the macros if you don't want to reveal your system. There has to be something that BA doesn't like.

Have you tried entering a trigger manually in a new spreadsheet, does this still work?
