Counting the number of time a specific word is in a field
I have a field that contains text as below. I want to make a calculation field that counts the number of times the word "Evolution" appears in the field. the field containg trhe text is wsdl_load_results. The field contains the functions loaded by a plugin fror my websites API functions. I want to count the functions so I can add a subscript to my start up that looks to see if any new functions get added by the web site developers and lets me know at start up.
Evolution_MarkOrderLine( MarkOrderLine_ServerID; MarkOrderLine_TokenKey; MarkOrderLine_Password; MarkOrderLine_SalesID; MarkOrderLine_EntityID )
Evolution_ProductDetailsEVO( ProductDetailsEVO_ServerID; ProductDetailsEVO_TokenKey; ProductDetailsEVO_Password; ProductDetailsEVO_ProductID )
Evolution_ProductDetailsSKU( ProductDetailsSKU_ServerID; ProductDetailsSKU_TokenKey; ProductDetailsSKU_Password; ProductDetailsSKU_SKU )
Thanks in advance.
