However it works with the following change: fun[x_] := 1/x; Button["DoIt", Print(a)fun[x]] Daniel -- Daniel Huber Metrohm Ltd.

If for example the definition of analyzer limits its arguments to particular types - e.g. x_String - then if you call the function with the wrong type of argument, nothing will happen. Possible suggestions: 1) Put the whole notebook, plus input file somewhere on the internet, and someone will probably determine what has gone wrong. 2) Test the code by calling Get and then calling analyzer without using the button. 3) Add some Print commands to analyzer to determine if it is being called, and how far it gets. I don't think this problem is connected with running out of memory. If the kernel runs out of memory, it will tell you. David Bailey http://www.dbaileyconsultancy.co.uk |
