In my reports, i set condition of groupheader in the OnBeforePrint event of this band. With some fields of my queries, is showed the error:

Could not convert variant of type (string) into type (double).

The field i use to set condition is a VARCHAR(15) field.
With other field of the same type, the report works fine.

Thanks.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
