Subject Re: calling part of .wfm from another .prg From Bruce Beacham <bbeacham@no-plm-lowman.co.uk> Date Mon, 3 Jan 2022 22:47:58 +0000 Newsgroups dbase.getting-started Not good. If you open the form in the ordinary way (rather than from another form or function), it will still see and use the public variable, whereas you actually want it to use the properties of its own form. You should read-up about encapsulation. Bruce On 02/01/2022 16:12, Milind Nighojkar wrote: > Thanks Bruce, > It worked with minor change insted of Parameter fm.
