HDFC Bank — not able to subscribe to hdfc amc ipo

Address:	Hyderabad, Telangana, 500084
Website:	hdfc net banking

I am trying since 3 days. I end up at the last page which shows up repearedly. My demat firm/agent is motilal oswal securities ltd (Mosl) who is a member of cdsl.
After entering cdsl, mosl and its id [protected]., i am not able to enter my own dp id number. This is the reason why i am unable to subscribe when i am entering my id in the relevant box, the box is not accepting and is blank.
Because of this glitch i am not able to subscribe to hdfc amc ipo. If you clarify immediately at least i can apply today. My mobile number [protected].
