----------------------------Instructions on how to make this validation to work
----------------------------
----------------------------    Items needed:
----------------------------        this script file
----------------------------        the ValidatePurchaseForm.vb class 
----------------------------
----------------------------For each Item you want to validate, do the following 
----------------------------    - add the field name you want to appear in the alert as a css class of the field itself, replacing spaces with "_" and slashes(/) with "~". 
----------------------------        (i.e. "Jesse Trimble/Kayla Stevens" would be entered as "Jesse_Trimble~Kayla_Stevens") 
----------------------------    - if you're taking any information where there is more than one field for that info (i.e. four credit card fields), add "rep" as a css class to each of those fields.
----------------------------
----------------------------Then do the following
----------------------------    - in the code behind, do a RegisterClientScriptBlock with the attachJSArray function from the class ValidatePurchaseForm.vb as the script parameter.  
----------------------------        the attachJSArray function takes a WebControl array of all of the fields you want to validate as a parameter
----------------------------        (i.e. attachJSArray(new WebControl() {me.txtField, me.cboField})    )
----------------------------    - in the code behind, do a RegisterClientScriptBlock with the attachCBOValues function from the class ValidatePurchaseForm.vb as the script parameter.
----------------------------        the attachCBOValues function takes a DropDownList array of all of the dropdowns you want to validate as a parameter
----------------------------        (i.e. attachCBOValues(new DropDownList() {me.ddl1, me.ddl2})    )
----------------------------    - in the code behind, add the following: "return doValidation(formElements);" to the "onclientclick" event of the submit button or link (must be an asp:Button or asp:LinkButton)
----------------------------
----------------------------    Validation should work from there!!
