**Note:** This article applies to WorkflowGen **versions 7.19.0 to 7.21.x**.

### Issue

When submitting a form that contains a textbox with a currency/numeric validator, and the configured language/culture uses a currency/numeric format not compatible with `en-US` (such as a comma as a decimal separator for `fr-CA` or `fr-FR`), you receive an error message stating that the value is invalid.

This is a regression bug due to the web form async mode feature that was introduced in version 7.19.0, which enables async mode by default on all `default.aspx` files generated by the Form Designer.

### Solution

A patch is available to resolve this issue. Download the patch [WorkflowGen.My v4.6.3](http://download.workflowgen.com/library/wfg-my/4-6-3/wfg-my.zip) then install the new assembly file into the webforms `bin` folder.

You will need to **copy and overwrite** your current `\wfgen\wfapps\webforms\bin\WorkflowGen.My.dll` file with the one from the patch.
