Using the concatenate function with complicated text

Hi,

I have a URL string which i'd like to edit using the concatenate function.
The address for example:
http://www.tase.co.il/TASE/Templates...&subDataType=0


The strings i'd like to replace are '00319012' and '000319'.
These numbers are the share id and company id. I have an excel file with share id's and company id's.
I tried to use the concatenate funtion in this way:

=concanate("http://www.tase.co.il/TASE/Templates/Company/CompanyHistory.aspx?NRMODE=Published&NRORIGINALURL=%2fTASE%2fGeneral%2fCompany%2fcompanyHistoryData%2ehtm%3fsubDataType%3d0%26companyID%3d002215%26shareID%3d01115112&NRNODEGUID=%7b6BC1C307-4BF8-45C7-99EB-07D3F49DDAA0%7d&NRCACHEHINT=Guest&shareID=",A8,"&companyID=",Q8,"&subDataType=0")

but I get an error message.

Can someone help me solve the problem?



Thank you,

Moty
