I have a field name "BigText" with type long with length 0 ( for unlimited chars) on record MyPrueba, and I have a page where I use a Long Edit Box, on the same record MyPrueba I have a field named "PasteInfo". I copy a lot of text from excel to field "BigText" and I have a PushButtom "PasteInfo" How I do if I want to filter the text, its to say eliminate the characters and only left digits. I only want to assign to a variable but I'm not get the value. Note I want to filter before save.

Example:
On field pushButtom on FieldChange I have the following code:

REM &Cadproceso = GetField();
&Cadproceso = Myprueba.BigText.value;
&Longcad = Len(&Cadproceso);
MessageBox(0, "", 0, 0, "The text is " | &Cadproceso | " And the lenght is " | &Longcad );

or...

If I can to get the value from htmlarea and after assign to longChar. I am trying with the following, But I dont get the value:
Local string &DQ;

&DQ = Char(34);

&CodHtml = &CodHtml | "" | Char(10);
&CodHtml = &CodHtml | "function Test(element1,element2)" | Char(10) | "{" | Char(10);
&CodHtml = &CodHtml | "var text1 = document.getElementById(element1); ";
&CodHtml = &CodHtml | "var text2 = document.getElementById(element2); ";
&CodHtml = &CodHtml | "text2.value = text1.value; }";
&sHTML = &sHTML | "" | Char(10);

&sHTML = &sHTML | " ";
GM_PRUEBATRANSF.GM_CODHTML = &sHTML;
MessageBox(0, "", 0, 0, "La cadena es " | GM_PRUEBATRANSF.GM_LISTADEMPLEADOS);
